Broadleaf weeds identification: common types with images

What kind of weed are you dealing with? If weeds have invaded your property, this is the first question you need to answer. By correctly identifying the invasive plant, you can use proper and effective eradication techniques.

Unfortunately, weed identification, especially when dealing with broadleaf weeds, is not easy. There are several invasive species, and some are very easy to confuse with others.

But worry not! Here is a list of the most common types of broadleaf weeds with their scientific names. It covers the essential information you need to identify different broadleaf weeds.

What are broadleaf weeds?

It is essential to look at broadleaf weed’s definition before looking at the various types of these invasive plants.

Broadleaf weeds are invasive plants with broad leaves that usually grow from a stem. The leaves typically have a central vein at the center, with other small veins that branch out.

These weeds are also very conspicuous and stick out. Therefore, you can identify broadleaf weeds by photo comparison with ease.

20 most common broadleaf weeds

These are some of the most common broadleaf weeds that you might come across in your yard.

1. Chickweed (Stellaria media)


Are chickweeds broadleaf weeds? Yes, they are. They are an annual and perennial flowering plant native to the European region. However, they have spread and adapted to various areas worldwide.

Chickweeds are low-growing plants with hairy stems. They have broad, long and oval-shaped leaves pointed at the tip. They also produce small, white, star-shaped flowers.

Chickweeds are a beneficial weed plant due to their several health (herbal) benefits. However, they are an invasive species, easily proliferating moist and fertile soils. A single chickweed plant can produce several thousand seeds, making them a nightmare to kill.

2. White Clover (Trifolium repens)
