Ajuga is a genus of low-growing, herbaceous evergreen to semi-evergreen perennials that grow 10-30 cm tall. Species can be identified by their glossy, oval-shaped leaves in tight rosettes with green, purple, silver, bronze colour or variegated in different colours and showy, upright whorled spikes of two-lipped, tubular blue-violet flowers.

Stems are square in cross-section, stoloniferous and rhizomatous, rapidly spreading along the soil surface to form dense, carpet-like mats. In the bloom season, vertical flowering stems emerge above the foliage.

Bugleweed leaves are glossy, oval to spatula-shaped, forming dense basal rosettes. Depending on the specific cultivar, the foliage can be green, purple, bronze, or silver and variegated in white, cream, pink, red, or yellow.

Basal leaves are obovate to elliptical with wavy edges, about 7 cm long and 2 cm wide, while the leaves along the stalk are opposite, ovate, and smaller in size. The foliage remains evergreen, providing a colorful groundcover throughout the year.

Flowers are two-lipped and tubular, borne on dense vertical spikes about 15 cm long. They can be blue-violet, blue, pink, purple, or white in colour. Flowering occurs in spring to early summer in many regions. 

Reproduction, Dispersal, and Life Cycle

• Life Cycle: Perennial 
• Seeds: A single plant can produce hundreds of seeds per growing season
• Climate: Thrives best in temperate and cool subtropical climates
• Dispersal: Falling, vegetative, animal, and human activity

Bugleweed behaves as a hardy perennial with established colonies persisting for many years where suitable conditions prevail. The plant reproduces through vegetative and seed production. 

The seeds are found within dry nutlets and typically fall beneath the parent plant to begin germination. Small animals, birds, and insects may transport the seeds attached to feathers and fur to new areas. Human activity through nursery production and landscape cuttings has also contributed to the introduction of the plant in different regions globally.

While the species and cultivars in the Ajuga genus may produce seeds regularly, the primary means of propagation is through vegetative growth, where stolons that root at the nodes to produce new plants.

The plants prefer moist soil, full sun, and deep shade. They can tolerate partial shade and can tolerate seasonal drought once established.

• Glechoma hederecea
• Prunella vulgaris 
• Veronica peduncularis 

Uses

1. It is grown as a groundcover plant for shady and partially-shaded landscapes.
2. Ajuga is a popular plant in rock, woodland, and pollinator gardens for its beautiful foliage, as it is a favorite of hummingbirds, bees, songbirds, and moths.
3. Bugleweed is also grown as a border plant along paths and garden beds.
4. The plant is also grown on slopes and steep banks to prevent erosion.
5. Common Bugleweed was used as traditional medicine in European folklore to improve hyperpigmentation, skin hydration, and to prevent alopecia. 

Impact on Farms and Environment

Bugleweed is a beneficial ground cover plant that can also prevent soil erosion in various settings. It is also not considered a significant agricultural weed. 

However, some species can escape and spread aggressively in favorable conditions. These new populations may suppress other plants in nurseries and ornamental landscapes, crop lands, and pastures. 

Constant monitoring and early intervention is required to keep escaped populations from establishing in unwanted areas. 

Control

• Mechanical control: Hand-pulling, digging, and mulching
• Cultural control: Edge trimming and monitoring
• Chemical control: Treatment with a non-selective herbicide like glyphosate

For small infestations, hand-pulling or lifting the mats and digging the runners is a viable option in achieving effective control over Bugleweed. Repeat pulling of new plants is required in the next few seasons to prevent reestablishment. 

In ornamental beds, applying a thick layer of mulch can suppress new stolons and the establishment of seedlings. Edge trimming and routine pruning of runners can help contain the spread in the desired areas. 

Where pulling or mulching is impractical, repeat spot treatments of a non-selective herbicide like glyphosate or a post-emergent herbicide combination like 2,4-D +Dicamba + MCPP or Triclopyr can help eradicate established colonies.

Read the product label and strictly follow the usage instructions as directed for the best results.

• Stems: Slender, creeping, highly branched, and growing across the soil surface
• Flowers: Small, star-shaped, pale blue to white blooms
• Roots: Fibrous root system

Swamp Isotome is an evergreen herbaceous creeping plant that grows 2-8 cm long while spreading about 30-60 cm wide. You can easily recognize the species by its slender, low-growing stems, small, bright green, rounded leaves with a mat-forming habit, and white to pale blue, star-shaped blooms.

Stems are slender, creeping, and highly branched, allowing the plant to spread rapidly. Combined with underground rhizomes, it forms sprawling, dense mats that easily suppress other low-growing plants. 

Isotoma fluviatilis leaves are tiny, alternate, bright-green, oblong, elliptic, or linear, although the lower leaves may be obovate or ovate in shape. They are typically pubescent or sometimes glabrous and about 5-20 mm long and 2-8 mm wide.

Blue Star Creeper flowers are small, star-shaped, five-petaled blooms that grow on the side of stems. They are pale blue to white-blue, measuring 8-15 mm wide. Due to its sprawling nature, the flowers form a distinctive carpet of colour during the blooming season, which is typically between November and March.

The seed is extremely tiny, brown to black, elliptical, with a slightly wrinkled texture. 

Reproduction, Dispersal, and Life Cycle

• Life Cycle: Perennial 
• Seeds: A single plant can produce thousands of seeds
• Climate: Thrives best in cool to warm temperate and mild subtropical climates
• Dispersal: Falling, vegetative means, and human activities

Isotoma fluviatilis behaves as an evergreen perennial or semi-evergreen herb. A single plant can produce hundreds to thousands of seeds, depending on the prevailing environmental conditions.

The majority of the seeds typically fall beneath the parent plant and readily germinate when they come into contact with moisture and adequate light. 

However, the species primarily disperses vegetatively through creeping stems that root at the nodes. These nodes produce new shoots continuously to allow for rapid colonization. 

Human activities, including nursery production, sale, and landscaping projects, have also enabled the spread of the plant in new environments. 

Blue Star Creeper thrives in moist to wet, well-drained, sandy to loamy soils and partial shade. The species can tolerate short drought seasons. 

Similar Plants

• Pratia nummularia
• Veronica repens
• Lobelia angulata
• Soleirolia soleirii

Uses

1. It is grown as groundcover for gardens and landscapes, including between pavers, ponds, decks, edges, and rockeries.
2. The species can be used as a lawn substitute in low-traffic areas.
3. Blue Star Creeper is a popular plant in pollinator gardens to provide pollen for small, beneficial insects.
4. The plant can be incorporated in water-wise landscaping in regions with moderate moisture availability.
5. Creeping Isotome is grown on sloped areas and moist banks to prevent erosion.

Impact on Farms and Environment

Isotoma fluviatilis has minimal negative impact when grown responsibly. It helps sustain livelihoods through nursery production, retains moisture in garden beds, provides dependable perennial groundcover for various landscaping settings, and suppresses weed establishment.

That said, highly fertilized or escaped populations can spread to adjacent garden beds and disturbed habitats, but it is typically not considered a major invasive plant species. 

The creeping plant is also not a concern in agricultural settings and rarely affects farming operations. 

Control

• Mechanical control: Hand-pulling, digging, and mulching
• Cultural control: Regular trimming of garden edges
• Chemical control: Apply herbicides like Dicamba, triclopyr, or glyphosate

While Blue Star Creeper is mostly grown intentionally, it can escape and become a pesky weed in garden settings. 

In this case, measures like hand-pulling and digging can be effective for small infestations. Since the stems root at the nodes, it’s important to dispose of all the fragments properly to prevent regrowth.

Regular trimming of garden edges can also help limit the spread to unwanted areas. Monitor the areas close to new plantings to allow for early intervention where needed.

For larger infestations, repeat applications of chemical herbicides containing triclopyr, dicamba + 2,4-D, or spot treatments of glyphosate can be effective.

Ensure that you read the product label and use the chemical herbicide as per the instructions given to avoid negatively impacting your desirable garden plants.

• Fruits: Small, berry-like drupes, orange to red in maturity
• Stems: Upright, thick, fleshy, cane-like stems
• Flowers: Inconspicuous, white to pale green spadix surrounded by a spathe
• Roots: Fibrous root system

Dumb Cane is an evergreen, broadleaf perennial in the Araceae family that can grow 1-3 m long, depending on the cultivar. It is widely grown for its large, shiny, attractive foliage, typically marked with white, yellow, cream, and green variegation. It is easily recognizable by its large, broad, oval attractive leaves and thick, fleshy, cane-like stems.

Stems are upright, thick, and cane-like, hence the name “Dumb Cane”. The prevalent thickness helps support the large leaves. When plants mature, the leaves drop, exposing the stout stems underneath.

Dumbplant leaves are alternate, large, broad, glossy, with pointed tips and about 20-60 cm long. The most distinguishing feature is the attractive variegation consisting of white, cream, yellow, and various shades of green across the leaf blade. 

They grow in a spiral pattern along a thick petiole that wraps around the stem from the base.

Dieffenbachia produces an inconspicuous inflorescence consisting of a white to pale green spadix (flower-bearing structure) surrounded by a spathe (modified leaf). 

The seed is small, round, and light brown to tan in colour when mature. 

Reproduction, Dispersal, and Life Cycle

• Life Cycle: Perennial 
• Seeds: It is not a prolific seed producer
• Climate: Thrives best in tropical and subtropical climates
• Dispersal: Split-falling, animals, and human activity

The Dieffenbachia plants are long-lived, evergreen, herbaceous perennials. Plants can survive many years while producing new leaves from the stem apex every growing season. 

Many species are not prolific seed producers, and the seeds produced in native habitats often fall beneath the parent, are dispersed by animals, and through human cultivation. These seeds germinate in moist and warm conditions. In cooler seasons, indoor plants experience slow growth

While the plant can produce viable seeds, in horticulture, it is primarily propagated vegetatively. Broken stem sections readily root in ideal environmental conditions. As a popular houseplant, it is widely distributed through cuttings and nursery production.

Dieffenbachia thrives in well-drained, moist soil, partial shade, and moderate to high humidity. The plant species can tolerate seasonal droughts but are highly sensitive to frost and prolonged cold conditions. 

Similar Plants

• Sygonium species
• Alocasia species
• Maranta species

Uses

1. It is an important indoor plant used to brighten homes, offices, and other indoor areas.
2. The plant species supports many livelihoods through nursery production and sale, as it is one of the most sold ornamental plants worldwide.
3. Some low-growing cultivars are used as tall groundcovers.
4. The Dumb Cane is grown in closed environments to clear toxic organic substances like toluene.
5. Despite its high toxicity, Dieffenbachia has been used as traditional medicine, food, and as a tool of punishment by various tribes in the Amazon.

Impact on Farms and Environment

Spotted Dumbcane is not considered an invasive plant where it is grown as an ornamental plant. However, escaped populations in tropical regions can establish in disturbed sites and outcompete native vegetation. 

In native habitats, Dieffenbachia grows in large colonies but rarely becomes a problematic weed. Such habitats include forests, disturbed areas, and stream banks.

As one of the most toxic plants to humans, it is not recommended for outdoor cultivation. Indoor cultivation also requires careful handling to avoid accidental exposure. 

Dieffenbachia sap contains calcium oxalate crystals known as raphides that can cause skin irritation. Ingestion can cause mouth swelling, pain, difficulty speaking, and temporary loss of speech, hence the name “Dumb Cane”. It is also toxic to dogs and cats if ingested.

Control

• Mechanical control: Pulling and digging
• Cultural control: Proper disposal of garden waste

Young plants and seedlings can be removed through pulling or digging. Ensure that the root system is completely removed to prevent regrowth. For larger clumps, cut the upper portions and excavate the underground parts carefully. Wear protective gloves to prevent irritation to the skin and eyes. 

Proper disposal of garden waste is an important cultural measure in preventing accidental establishment. Maintaining healthy native vegetation can also discourage Dieffenbachia growth, because it is not a prolific producer.

• Common Names: Siam Weed, Christmas Bush, Jack in the Box, Triffid Weed, Bitter Bush, and Acheampong Leaves. 

Nativity and Distribution

Siam Weed is native to the tropical and subtropical Americas, including Texas and Florida in the United States, Mexico, and the Caribbean.

Today, the perennial has been introduced to other regions, including West Africa, Asia, and parts of Australia.

Physical Characteristics

• Leaves: Opposite, triangular to elliptical, with serrated edges, 4-10 cm long
• Fruits: Black to dark-brown, achene with a pappus, 4-5mm long
• Stems: Upright, soft, green with fine hairs, upper stems, and woody at the base 
• Flowers: Small, pale pink to white tubular blooms
• Roots: Fibrous root system

Chromolaena odorata is a fast-growing, perennial multi-shrub in the Asteraceae family that can grow between 2.5m in open areas to 10m when climbing on other plants. You can recognize the plant by its triangular, aromatic, velvety-haired leaves and pale pink to white tubular flowers.

Stems are mostly upright, green, soft on the upper side and woody at the base, with fine hairs. When located in shady areas, the plant behaves as a creeper, climbing neighboring vegetation for support, achieving a height of up to 10m.

Siam Weed leaves are opposite, triangular to elliptical, about 4-10 cm long and 1-5 cm wide, with serrated edges. They feature three prominent veins that run from the leaf base, resembling a pitchfork, hence the name, Devil Weed. When crushed, the leaves emit a strong, pungent odor, which inspires the name ‘odorata’.

C. odorata produces small, tubular flowers borne on dense terminal clusters, with each holding about 10-35 blooms. Individual florets range from pale pink, lavender, or white and are an important source of nectar. Flowering occurs in the cooler or drier months, depending on the environment.

The seeds are small, narrow, elongated achenes, dark brown to black, with pappus (whitish brown bristly hairs), and about 4-5 mm long.

Reproduction, Dispersal, and Life Cycle

• Life Cycle: Perennial 
• Seeds: A single plant can produce 80,000 to 1,000,000 seeds per season
• Climate: Thrives best in tropical and subtropical climates
• Dispersal: Wind, animal, and human activity

Chromolaena odorata behaves as a perennial shrub, often surviving for many years. Seedlings grow rapidly during favorable conditions (sometimes up to 3 cm a day) and mature plants flower annually. The upper parts of the plant die off eventually, leaving behind the roots and lower stems for regeneration. 

Siam Weed is a prolific seed producer, with each plant producing 80,000 to over 1,000,000 seeds per growing season, depending on the environmental conditions and plant size. 

The seeds have bristly hairs (pappus) that allow them to be carried off to long distances by wind currents. They are also dispersed by animals and human activity through contaminated vehicles, machinery, seed, and movement of soil. The species also reproduces by vegetative means through nodding at the branches.

C. odorata seeds have a 30%-60% viability, with only 2% germinating immediately, while the rest go into dormancy. The weed prefers tropical and humid subtropical climates, thriving in full sun and partial shade. It is common in open areas, forest edges, pastures, crop lands, plantations, and abandoned sites.

4. In Africa, the boiled herb is used for cough relief, and when mixed with guava and lemongrass, it is used for protozoan infections. 
5. The leaves are consumed as a vegetable for their rich nutritional profiles, including fiber, protein, and essential minerals. 
6. C. odorata is used as green manure in some agricultural systems.
7. It can be planted in degraded lands to prevent soil erosion, although under strict supervision.

Impact on Farms and Environment

Siam Weed is considered a serious weed in agricultural systems. It typically affects perennial crops such as coffee, cocoa, palm, sugarcane, teak, and rubber. Since it is a fast-growing plant and domineering in terms of spacing and nutrient competition, it can smother desirable crops. 

In shifting cultivation, it may be a preferred weed as it is easier to clear and can prevent the growth of other pesky weeds like Imperata cylindrica. However, this fallow system measure should be taken with caution as its risks far outweigh the benefits.

The weed hosts insects like the Variegated Grasshopper (Zonocerus variegatus) and other pathogens that can affect crop leaves, flowers, and fruits, reducing crop yield and quality.  

Chromolaena odorata also invades pastures, reducing cattle carrying capacity. It easily overtakes overgrazed areas, yet it is toxic to cattle because the leaves contain high nitrate levels.

In forest edges, riverbanks, wildlife reserves, and other natural habitats, Siam Weed can displace native vegetation, negatively impacting biodiversity and threatening livelihoods. 

The species’ impenetrable thickets can also be a fire hazard in regions with prolonged dry seasons.

Control

• Mechanical control: Hand-pulling and digging
• Cultural control: Establish competitive pasture grasses
• Biological control: Introduction of mites and moth larvae
• Chemical control: Application of herbicides such as glyphosate and triclopyr

Hand-pulling is a viable option for removing seedlings and young plants. The root system must be dug out to prevent regrowth. Two repeat clearances are also recommended every growing season to ensure effective control. Applying herbicides like triclopyr at this stage can also enhance weed control.

In pasture lands and perennial plantations, introducing competitive pasture grasses, native competitive weed species, and dense ground cover crops has been shown to reduce seed establishment. 

Several attempts to introduce biological agents for C. odorata have shown limited but promising results over the years. These include the seed-feeding weevil, Apion brunneonigrum, in West Africa and Asia, and Pareuchaetes Pseudoinsulata, in South Africa. 

More research is ongoing to find biological control agents that can provide effective control against all strains of the weed across all continents.

Systemic herbicides containing active ingredients like glyphosate and triclopyr can suppress infestations if applied in the early growth stages. However, several repeat applications are required to counter resprouting from seed banks.

• Fruits: Dry capsule, globose, hairless to densely hairy, and brown in maturity
• Stems: Upright, fleshy, cane-like with spotted patterns
• Flowers: Yellow tubular blooms with orange-red stripes, about 5 cm long
• Roots: Rhizomatous root system

Costus pictus is a rhizomatous herb that typically grows 60-90 cm tall and up to 2.5m in some conditions. You can easily identify the plant by its spiraling stems, long, glossy leaves spiraling around the stem, and showy, yellow flowers with orange-red stripes, emerging from corn-like bracts.

Stems are erect, glabrous, cane-like structures that grow in a tight spiral pattern. They feature distinct red tinges with mottled, striped, and spotted patterns. While they may resemble real stems, they are actually pseudostems that form from overlapping leaf sheaths.

Painted Spiral Ginger leaves are simple, alternate, elliptic to oblong, about 10-30 cm long and 2.5-6 cm wide, with entire margins. They are glossy green on the upper surface, with the underside typically featuring a lighter coloration. The leaves spiral around the stems, giving the plant a unique architectural form.

C. pictus produces yellow, tubular flowers with orange-red stripes, about 5 cm long that appear on compact, globose to ovoid, cone-like bracts. The blooms resemble paper lanterns and typically last for one day, with the inflorescence bearing two new flowers every day.

Flowering occurs throughout the warmer months – late spring to early autumn. In warm, tropical environments, it can flower continuously for much of the year. 

The seed is small, black, and enclosed in white arils, occurring in a dry capsule.

Reproduction, Dispersal, and Life Cycle

• Life Cycle: Perennial 
• Seeds: Produces a few hundred seeds annually
• Climate: Thrives best in warm, tropical climates
• Dispersal: Splitting, animals, human activity, and vegetative propagation

Painted Spiral Ginger behaves as a perennial herb. When favourable conditions arise, new shoots emerge from the underground rhizomes, producing foliage and flowers throughout the growing season. 

The stems die off in colder months as the rhizomes persist to restart the new growth when ideal conditions resume.

The seeds are produced in a dry capsule that breaks open when mature. They fall beneath the parent plant to begin germination, while other seeds are dispersed by animals and humans through ornamental and medicinal cultivation to new areas. 

Spiral Ginger also reproduces through vegetative means, where rhizomes spread outward, producing new shoots that form dense colonies. 

The perennial herb thrives best in warm, tropical climates with full sun or partial shade, and moist, well-drained soil conditions. It can’t tolerate frost and prolonged cold conditions.

Impact on Farms and Environment

Costus pictus is not considered an invasive or problematic plant in agricultural settings. When cultivated responsibly, it can provide income for growers specializing in herbal products. That said, it has the potential to escape and form formidable colonies if left unchecked. 

In the environment, it is an important nectar resource for pollinators, making a positive contribution towards plant diversity in various habitats. 

Control

• Mechanical control: Hand-pulling and digging
• Cultural control: Maintaining dense ground cover

For small populations, hand-pulling and digging of the rhizome portions can control the weed. Dispose of all remaining fragments properly to prevent regrowth. Repeated monitoring is also recommended to prevent regrowth from overlooked rhizomes.

For long-term control, consider maintaining a dense ground cover and reducing soil disturbance to limit the spread of seeds and germination.

• Stems: Upright, square, purplish green to dark near the flowering areas
• Flowers: Showy, deep blue, two-lipped tubular flowers, 2.5-5 cm long
• Roots: Fibrous root system

Black and Blue Salvia is a herbaceous perennial subshrub in the mint family that can grow up to 0.9-1.8 m with a spread of 2-5 feet wide in maturity. It is identified by its showy, two-lipped, deep-blue blossoms, dark to purplish green stems, and wrinkled, ovate leaves with a minty scent.

Stems are upright, square, ridged, hairless, and purplish green to dark near the flowering areas. Young stems are typically flexible, becoming woody at the base as they mature. They are also accompanied by rhizomes that allow the plant to spread horizontally and regenerate after dormancy. 

Anise Sage leaves are opposite, ovate to triangular-ovate, dark green on the top side and medium green on the underside, about 5-12 cm long. The leaf surface is wrinkled and pointed, with serrated margins. 

When crushed, the foliage produces a mild anise scent, hence the name Anise-Scented Sage.

S. guaranitica produces showy, deep, two-lipped, cobalt-blue flowers 2.5-5 cm long. The tubular blooms are borne in terminal racemes, 25-35 cm long, and appear in sequence over an extended period of time.

The seeds are small (poppy-sized), dark brown to black in colour. 

Reproduction, Dispersal, and Life Cycle

• Life Cycle: Perennial 
• Seeds: A single plant may produce a few hundred seeds per season
• Climate: Thrives best in subtropical and warm temperate climates
• Dispersal: Falling, water, animals

Salvia guaranitica is a herbaceous perennial that resumes growth through crowns in spring, flowers in midsummer, with the top portions dying back in colder months. 

The seeds develop within four nutlets in the calyx. The majority are dispersed by falling beneath the parent plant for germination, while the rest are dispersed by animals and moving water.

Since the wild plant’s seed production is inconsistent to support horticultural production, the plant is propagated through rhizomes.

Black and Blue Salvia thrives in humid subtropical and mild temperate climates. It prefers full sun to partial shade, humus-rich, evenly moist, and well-drained soil. 

The perennial can tolerate medium drought once established but prolonged freezing temperatures may damage the rhizomes and crowns.

 Similar Plants

• Salvia azurea
• Salvia farinacea
• Salvia nemorosa
• Salvia leucantha 
• Salvia mexicana

Uses

1. Brazilian Sage is a popular ornamental plant, often planted in mixed beds, borders, and cutting, cottage, and rock gardens.
2. It is a strong pollinator plant and hence grown in pollinator gardens to support hummingbirds, butterflies, bees, and other beneficial insects.
3. It is a popular addition for water-wise landscaping as it can withstand mild drought and deer browsing once established.

Impact on Farms and Environment

Salvia guaranitica is not considered an agricultural weed as it hardly interferes with desirable plants. Its ability to attract pollinators can prove beneficial to desirable fruit and vegetable crop farms. 

However, the perennial is prone to insect problems with aphids, whiteflies, and spider mites being the most common predators. Disease problems include rust, stem rot, and fungal leaf spot. If planted close to desirables, routine checks and quick control measures should be implemented to prevent the spread of the insect and disease problems.

Its prolonged blooming period makes Anise Sage a reliable source of food for pollinators in late summer through to autumn, thereby contributing to biodiversity and supporting local wildlife populations.  

Control

• Mechanical control: Hand-pulling and cutting
• Chemical control: Broadleaf herbicide application

Where quick removal is desired, hand-pulling and digging out the established clump can provide effective results. Ensure that you dispose of the rhizomes correctly, as remaining fragments may resprout. 

In managed gardens, cutting the clumps down to size or removing them entirely during dormancy is recommended.

Cutting the stems before flowering and seed production can also limit the spread of the shrub. However, repeated treatments are necessary during the growing season to achieve effective control.

Where manual removal is not a viable option, spot treatment of broadleaf herbicides like 2,4-D, Dicamba, glyphosate, or MCPA can help eradicate the unwanted plants.

The herbicides should be applied according to the instructions provided to avoid negative impact on pollinators and desirable ornamentals or crops.

Nativity and Distribution

Azure Blue Sage is native to the central and eastern regions of North America. The native range includes the states of Kansas, Tennessee, Missouri, Nebraska, Georgia, Florida, Arkansas, the Carolinas, and Northern Mexico. 

Physical Characteristics

• Leaves: Simple, linear, ovate to lanceolate, grayish-green in colour, 7-10 cm long
• Fruits: Mottled, ovoid nutlets 2-3 mm, brown to copper in colour
• Stems: Upright, slender, and square in cross-section 
• Flowers: Showy, sky-blue, two-lipped tubular flowers, 6-12 mm long
• Roots: Tap root

Azure Blue Sage is a tall, delicate, herbaceous wildflower in the Lamiaceae family that grows between 3 and 5 feet tall. It is native to central and eastern North America and Northern Mexico. It is easily identified by its showy, azure-blue flowers, narrow grayish-green leaves, and square stems.

Stems are square in cross-section, characteristic of the Lamiaceae family. They may be branched or unbranched and typically arise from a thick crown. While they are mostly upright, they can also appear floppy when flowers are in full bloom.

Azure Sage leaves are simple, linear, ovate to lanceolate, and oppositely arranged along the stems. They are typically grayish-green to silver, with smooth to slightly toothed margins, and can grow 7-10 cm long. The foliage has an aromatic scent and taste, hence the name.

S. azurea produces showy, blue, two-lipped tubular flowers 0.6-1.3 cm long. The individual blooms are arranged in loose terminal spikes and feature 4-5 fused petals. Flowering occurs from summer into fall.

The seeds are small, brown to dark, and nutlet-type in appearance. 

Reproduction, Dispersal, and Life Cycle

• Life Cycle: Perennial 
• Seeds: A single plant can produce 500 – 1,000 seeds
• Climate: Thrives best in temperate climates
• Dispersal: Self-splitting, wind, and animals 

Pitcher sage is a long-lived herbaceous perennial with new shoots emerging in spring and the cycle ending with die-back of the above-ground portions after frost in late autumn and winter.

Each seed pod contains four nutlets, with each nutlet containing one seed. Since mature plants bear numerous spikes, a single plant can readily produce hundreds to thousands of seeds annually. 

The seeds are mainly dispersed through barochory – a mechanism where the seeds fall near the plant parent once the flower heads mature. Other secondary means of dispersal include wind, which carries the lightweight seeds to further distances, while the animals disperse them by carrying them on their fur. 

Human activities such as horticultural cultivation and roadside maintenance have also contributed to the dispersion of the wildflower to new areas. 

Salvia azurea thrives best in temperate climates, in full sun, moist soil with good drainage, sandy or shallow-rocky soil, and moderate to low humidity. The plant can tolerate drought, poor soils, and occasional flooding. However, it can’t tolerate prolonged waterlogged soils. 

Similar Plants

• Salvia farinacea
• Salvia nemorosa 
• Salvia greggi
• Phlomis tuberosa

Uses

1. Azure Blue Sage is a popular ornamental plant in perennial borders, meadows, native, rocky, and cottage gardens.
2. It is grown in pollinator gardens as it attracts bees, butterflies, and hummingbirds.
3. Due to its deer and drought-resistance abilities, Azure Sage is also a popular selection for xeriscaping and deer-resistant planting. 
4. It can be grown to restore meadows and prairies.
5. Prairie Sage is used by indigenous communities as a traditional remedy for wound healing, tooth issues, and hormonal imbalance. 

Impact on Farms and Environment

S. azurea is not considered a significant agricultural weed. The growth may occasionally occur on roadsides and grazed pastures, but its populations rarely overtake wanted vegetation or interfere with crop production. It also has no significant pest or disease problems.

The wildflower generally has a positive environmental impact as a critical pollinator plant, providing abundant nectar when other floral resources become scarce in late summer and fall. 

It also improves prairie plant biodiversity and offers a sustainable solution in restoration projects because of its drought resistance abilities. 

Control

• Mechanical control: Pulling, digging, and repeated mowing
• Chemical control: Selective herbicides like Dicamba, Triclopyr, and 2,4-D

Since Salvia azurea is a desirable plant, control is rarely necessary. However, where removal is desired, you can hand-pull the young plants before they flower to prevent seed production. 

Digging out the crown and the entire root system can also help prevent regrowth. Another option for Azure Sage removal is frequent mowing to weaken populations. This strategy provides the best results when repeated over several growing seasons.

For dense populations, selective herbicides like dicamba, 2,4-D, and triclopyr can be used to suppress the wildflowers in managed landscapes. Ensure that you follow local regulations and the right timelines to avoid harming beneficial pollinators and surrounding native vegetation.

• Family: Ranunculaceae 
• Genus: Nigella
• Species: Nigella damascena
• Common Names: Love-in-a-mist, Ragged Lady, Fennel Flower, Jack-in-the-Green, and Katharine’s Flower

Nativity and Distribution

Love-in-a-Mist is native to southern Europe (France, Italy, Greece, Spain coastlines, and the Balkans), North Africa (Algeria, Morocco, and Tunisia), and Southwest Asia (prominently found in Lebanon, Syria, and Turkey). 

It has also been naturalized in other regions, including Australia, South Africa, New Zealand, and North America.

Physical Characteristics

• Leaves: Alternate, feathery, with a fennel-like appearance, and grow up to 1.5 cm long
• Fruits: Large, balloon-like capsule about 2-5 cm long
• Stems: Erect, glabrous, angular in cross-section, 20-70 cm tall
• Flowers: Solitary, 2-4 cm wide with showy 5-25 petal-like sepals
• Roots: Tap root system

Fennel Flower is a small to medium-sized annual herbaceous plant that grows 20-50 and up to 70 cm in cultivated gardens. It is a beloved cottage flower in temperate climates and is easily recognizable by its solitary blooms and fennel-like leaves. 

Stems are erect, slender and sometimes branching at the top and can grow 20-50 cm. In cultivated gardens, the plant can grow up to 70 cm long. They are glabrous, finely ridged, angular in cross-section, and green to blue-green in colour.

Love-in-a-Mist leaves are bright green, finely cut into narrow, thread-like segments up to 1.5 cm long, giving it a feathery fennel-like appearance. Basal leaves are more linear and tend to get more finely divided up the stem. 

The uppermost leaves form a lacy collar that surrounds the flower, which is a distinctive feature for this species. 

Nigella damascena produces solitary flowers borne on the tips of stems and branches, about 2-4 cm wide. They are typically bright blue to pale blue but can also appear in shades of pink, lavender, or white depending on the cultivar. 

The showy coloured parts are 5-25 petal-like sepals. True petals are inconspicuous and located at the base of numerous stamens. The flower centre features multiple stamens surrounding a compound pistil of about 4-7 erect carpels. Flowering occurs in late spring through summer, depending on the prevailing environmental conditions. 

The seeds are small, 2-3mm long, egg-shaped, wrinkled, and intensely black in colour. 

Reproduction, Dispersal, and Life Cycle

• Life Cycle: Annual 
• Seeds: A single plant can produce over 1,000 seeds
• Climate: Thrives best in cool to mild temperate climates
• Dispersal: Explosive mechanism, water, animals, and contaminated soil 

N. damascena is a true annual, completing its entire cycle within a single growing season. Each plant can produce several hundred or thousands of seeds that are mainly dispersed through explosive mechanism, water, or contaminated soil. 

Germination occurs in autumn to early spring when temperatures are cool. It prefers full sun, well-drained, and moderately fertile soil. The plant can tolerate a range of soil types from sandy to clay-loam. Once the seeds ripen, the plant dies due to the increased temperatures.

Love-in-a-Mist can tolerate frosty weather but does not tolerate waterlogging and humid or hot conditions. 

Similar Plants

• Nigella sativa
• Nigella arvensis
• Nigella hispanica
• Foeniculum vulgare

Uses 

1. Love-in-a-Mist is used as an ornamental in cottage gardens, rock gardens, borders, cutting gardens, and in pollinator gardens.
2. The seeds are aromatic and are used as a flavouring agent on bread and cheese in North Africa and along the Mediterranean.
3. The plant is used in traditional medicine for fever management, regulating menstruation, nasal decongestion, and easing digestive problems. 
4. Ripe seed capsules are used as a food source for birds like finches and sparrows.
5. The seeds are used to make an essential oil that inhibits enzymes that propagate chronic inflammation and tissue damage. 

Impact on Farms and Environment

Nigella damascena is considered a low-risk weed in terms of invasiveness and agricultural impact. However, where dense infestations occur, it can crowd out desirable plants and outcompete seedlings in disturbed soil.

Since the buried seeds can remain viable for several years, re-emergence in cultivated fields and seedbeds may require prolonged and expensive management.

In non-native environments, the plant can escape cultivation and invade areas such as roadsides, rocky and waste areas, and other disturbed sites.

All parts of the plant contain alkaloids that can cause mild toxicity in humans and livestock. It is recommended that you follow professional guidance when using the plant for medicinal purposes. 

Control 

Mechanical Control: Hand-pulling, hoeing, and mulching

Love-in-a-Mist is a non-aggressive plant that also features a shallow tap root, making it easy to eradicate. Pulling the seedlings or young plants from the roots is the best option. Ensure that you dispose of the seed capsule material. 

Other effective options include shallow hoeing of seedlings in spring or laying a thick layer of mulch to suppress germination of self-sown seedlings. This will also reduce the need for repeated handweeding.

They can be easily identified by their vibrant five-petalled flowers, typically blue but can also be found in white or pink shades. The flowers are borne on coiled racemes that uncurl as the flowers bloom. 

Myosotis/Cynoglossum is native to temperate Asia, Europe, and parts of North Africa. 

Forget-Me-Not Classification

• Domain: Eukaryota
• Kingdom: Plantae
• Phylum: Tracheophyta
• Subphylum: Angiospermae
• Class: Magnoliaspida
• Order: Boraginales
• Family: Boraginaceae
• Genus: Myosotis/Cynoglossum
• Species: Myosotis spp./Cynoglossum spp.
• Common Names: Forget-Me-Not, Scorpion Grass, Chinese Hound’s Tongue

Nativity and Distribution

Forget-Me-Nots are native to Temperate Asia, Europe, New Zealand, and parts of North Africa. However, due to horticultural trade and accidental movements, several species can be found in South Africa, parts of the United States, and Australia.

Physical Characteristics

• Leaves: Simple, alternate, oblong to lance-shaped, and about 1-10 cm long
• Fruits: Narrowly ovoid cluster of smooth nutlets 1-3mm long
• Stems: Creeping or erect, typically 15-50 cm long
• Flowers: Flat, five-petalled flowers with white or pink centres
• Roots: Fibrous root system

Forget-Me-Nots are biennials or perennial herbaceous flowering plants in the borage plant family. They have erect to spreading, or creeping stems that can grow 15-50 cm long depending on the species.

You can identify the plants by their narrow, oblong to lance-shaped leaves, tiny, sky-blue, white, or pink five-petalled blossoms and saucer-shaped corollas. 

Stems are erect to spreading, or creeping to branching, and can reach 50 cm in height for species like the M. sylvatica. They are slender and covered in small, fine hair that gives them a greenish-gray hue. 

Forget-Me-Not leaves are simple, alternate, and sessile on the upper stems. The leaves on the bottom may form a basal rosette with short petioles. Leaf blades are narrow, oblong to lance-shaped, about 1-10 cm long, with prominent midveins and smooth margins. 

Myosotis/Cynoglossum plants produce small, five-petaled flowers with rounded petals fused at the base. They are typically 5-8 mm in diameter. The most common Forget-Me-Nots are sky blue in colour with prominent white, pink, or yellow centres. However, some species produce white or pink flowers. 

These flowers are borne on elongate cymes that gradually uncoil as blooms open in spring through to early summer. 

The herbaceous plants produce small, flat, tear-drop shaped seeds that turn dark-brown or black in maturity. In some species, the seeds may have burs for easy attachment during dispersal. 

Reproduction, Dispersal, and Life Cycle

• Life Cycle: Annual, biennial, or perennial 
• Seeds: A single plant can produce 1,600 seeds
• Climate: Thrives best in cool, temperate climates
• Dispersal: Birds, animals, water, and humans

The life cycle of Forget-Me-Nots varies by species. However, most of the species, including Myosotis arvensis, Myosotis scorpioides, and Myosotis sylvatica, are short-lived biennials or perennials. For the biennials and short-lived perennials, this means that they grow vegetatively in the first year and set seed in the second year before dying. 

The seeds are mainly dispersed by birds, animals, and humans. The seeds contain burs that attach to fur, feathers, and clothing enabling wider dispersal. The commercial sale of the plants has also propagated the introduction of the species into new habitats. 

Other species like the Myosotis scorpioides, also known as the Water Forget-Me-Not, develops through rhizomes and stolons that root at the nodes, enabling it to anchor in waterlogged soils and spread vegetatively.  

These species thrive in cool, temperate climates with adequate moisture and shade. They thrive best in spring when temperatures are mild and do not tolerate hot, dry, or tropical conditions. 

Similar Plants

• Myosotis discolor
• Cynoglossum amabile
• Borago officinalis
• Veronica spp. 

Uses

1. The plants are used as spring ornamentals in wildflower meadows, rock gardens, woodland gardens, and as border plants.
2. Forget-Me-Nots are grown as ground cover in daffodil and tulip plantations to suppress weeds. 
3. The flowers are grown in pollinator gardens as an early-season pollinator resource.
4. In Europe, the plant is used as a traditional remedy for coughs, lung ailments, nosebleeds, and early onset symptoms of malaria. 
5. The flowers are edible and used in decorating baked goods and salads. 
6. The flowers are cut and prepared as floral arrangements in memorials and funerals in Europe.

Impact on Farms and Environment

While the Forget-Me-Nots are beloved spring plants in their native environments, introduced species can have significant ecological and agricultural impacts, especially if they escape the designated areas. 

Dense infestations are known to modify stream waterflow and to displace native vegetation. These may include understory herbs, sedges, and wildflowers, reducing plant diversity and altering community structure. Myosotis scorpioides, in Wisconsin, for instance, threatens the spike sedge (Eleocharis intermedia) and other wetland plants through resource competition. 

As pollinator plants, they can significantly alter native pollination dynamics by drawing away bees and other insects from native plants, leading to a decrease in native plant variety. 

The seeds have a prolonged dormancy of up to 30 years. This can make eradication difficult to achieve, allowing populations to re-establish even after years of constituent removal efforts. 

Consequently, they are a persistent weed in crop fields and pastures. The prolific seed production and long seed dormancy often lead to expensive and prolonged eradication efforts that may not yield much success. 

Some species contain pyrrolizidine alkaloids that cause livestock toxicity, including liver damage if consumed in large quantities. 

Control 

• Mechanical Control: Hand removal and hoeing
• Chemical Control: Apply herbicides 2,4-D, MCPA, and Chlorsulfuron

For small infestations, carefully pull the entire plant from the root as the stems tend to break easily. This will prevent further growth as well as seed set. Bag the material and do not compost it, as the seeds may be viable. 

Hoeing or cultivation is a viable weed removal option in agricultural settings. Disturb the soil before flowering to prevent seed set. However, if this is a recurring infestation, keep in mind that disturbing the soil may stimulate germination of soil-stored seeds.

Selective broadleaf herbicides like 2,4,D and MCPA can be applied in early winter to provide effective control in non-crop settings like pastures. 

For broad scale control, repeated application of sulfonyl urea herbicides like chlorsulfuron for at least three years has shown promising results in broad-scale control of M. sylvatica. 

Given the prolonged seed bank dormancy, long-term treatment and monitoring is highly recommended several years after the initial removal.

Considered one of the most invasive plant species in the country, officials are now paying close attention to the weed spread after documenting it in more than 44 counties across the state. A big increase from 15 counties in 2005. 

Why is the Kudzu Spreading Fast Across Indiana?

While Kudzu is not a new weed in Indiana, the spread has been slow over the past 20 years, mostly due to the local four-season climate. The harsh, cold winters, for instance, kill off the young growth before it can take hold and propagate.  

However, the climate is changing, bringing with it milder winters. These warmer conditions allow the invasive weed to grow and thrive across different landscapes.

“We have seen Kudzu doing potentially better in some locations where it wouldn’t have in the past, which has added some more challenges”, said Will Drews, a nursery inspector and compliance officer in the Indiana Department of Natural Resources. 

Why is Kudzu a Concern?

“Kudzu is a great poster child of showing what an invasive plant species has the capability of doing,” Drews has said. 

The weed dominates landscapes, displacing once vibrant and diverse biodiversity into a green monoculture. 

As it spreads, it poses more risks and challenges, such as:

• Ecological harm as it displaces native species and disrupts natural habitats.
• Reduced forest and plant health as the dense vines weaken trees and other vegetation, leading to greater susceptibility to other stresses.
• Increased property maintenance as homeowners battle to keep the weeds from encroaching on structures and damaging desirable trees and shrubs.

However, Indiana officials are hopeful in the fight against the insidious weed. They encourage more adoption of native plants in landscaping to minimize areas where Kudzu can grow and spread. 

In areas with high infestations, it’s imperative that once the weed is removed, the landowners cover the areas with native grasses and forbs, eliminating the chances of Kudzu regrowth.
