7 common weeds with pink flowers

Weeds are usually wild plants that grow in unwanted areas. Most are aggressive and can easily overwhelm other plants such as grass, flowers, and food crops.

As a result, many people spend a lot of time and money eradicating weeds from their gardens, lawns, backyards, and around their properties.

However, not all weeds are bad. On the contrary, some can be beneficial; for example, some are edibles, while others are excellent flowering plants.

Furthermore, some can have medicinal properties and several other benefits.

7 common weeds that have pink flowers

There are 7 common weeds that produce pink flowers:

1. Mallow

Mallow weed, or common mallow (Malva neglecta) as it is known, is one of the most widespread weeds you will come across.

It is an annual broadleaf weed commonly found in lawns, gardens, nurseries, and poorly maintained landscapes.

Mallow weed has bright green leaves with hairy stems. It typically grows by spreading but can grow upright in favourable conditions. It also produces flowers, which are light pink or white.

The weed is considered invasive as it has a robust taproot system, which guarantees its survival even under harsh conditions.

While mallow is a weed plant, it also has several beneficial properties. You can forage it for its medicinal properties, particularly the roots that have anti-inflammatory benefits.

Mallow is also edible (roots, stems, leaves, flowers, and fruits). It is highly nutritious, rich in vitamin A, B, and C, and contains calcium, potassium, and magnesium.

2. Clover

Clover (Trifolium ssp.) is a perennial wild flowering plant. It is commonly found in lawns and flower beds and is regarded as a weed as it is invasive in poorly maintained areas.

It is also hard to eradicate since it can easily survive mowing and some types of herbicides. Clovers are easy to identify as it is one of the few weeds with small pink flowers you will come across.

The flowers bloom around early spring and form a cluster that appears like a small ball of light pink petals. The plant also has three-lobbed leaves, which are petal-shaped.

While finding a clover plant in your garden or lawn can be concerning, the plant does offer several benefits.

First, it is a flowering plant that can provide a nice appearance to your landscape. It is also a good source of nectar and can help pollinate your crops.

Lastly, clover is a nitrogen-fixing plant that enriches the soil and has a deep root system, preventing soil erosion.

If these benefits are nothing compared to the damage this plant has done to your lawn, follow these clover removal techniques.

3. Joe Pye weed

Joe Pye weed is among the most common tall weeds with pink flowers. You can quickly identify it by its towering size, with the plant reaching up to 7 feet or more.

Some people consider the Joe Pye plant a weed as it has thick and deep rhizomes that help it spread. It also produces many seeds, which can scatter far.

However, the plant has several benefits. It is attractive and, therefore, a good ornamental plant that will help brighten your landscape.

Non-stinging hairs on the bottom part also cover the leaves. It blooms beautiful flowers, which can appear in pink, red, and purple shades.

Dead nettle is considered an invasive weed plant, as it can produce several thousand seeds, which will easily overwhelm other plants or grasses.

However, it offers several benefits, making it worthwhile to cultivate. For example, its pink flowers and silvery leaves are quite attractive.

It is also edible and foraged for its leaves, which taste similar to spinach when cooked.

It produces many seeds scattered far and wide by wind, wildlife, pets, and human beings. However, it is cultivated in some areas for its medicinal properties.

In folk medicine, it treats diarrhoea, toothaches, and nose bleeds. Furthermore, you can use the plant’s leaves as an insect repellent by crushing them and rubbing them over your body.

6. Dove’s-foot crane’s-bill

You can identify it by its tall reddish stems (which can reach up to 2.5 meters high) and bright pink flowers.

Rosebay willowherb is an invasive plant that can spread far wide through its root system. As a result, it can easily take over large areas of poorly maintained landscapes.

However, it also does offer several benefits. To start with, it is an ornamental plant that can improve the curb appeal of your property.

It also provides pollen to wildlife and nectar to bees, which in turn help to pollinate other crops.

Conclusion
