Red Clover (Trifolium pratense) is the familiar plant with purplish flowers (and sometimes white). It grows in lawns, gardens, and roadsides. Also known as Dutch Clover.
Note that it may take several seasons or years to eliminate the weeds and for your lawn to grow in healthy and dense. To keep a lawn in top shape takes constant effort throughout the seasons, and any lackadaisical care will likely increase weed infestation.
Wild Violet (Viola sororia) is another common plant that produces tiny purple flowers in your grass. Also known as forget-me-nots, there is some debate as to whether wild violets are an actual weed or not.
Henbit (Lamium amplexicaule) is one of the most common purple flowering weeds known. It is an edible plant that got its common name because of its popularity with chickens.
Once weeds have taken hold, you may get rid of them manually by hand pulling or digging; chemically by using an herbicide or pre-emergent herbicide; or by starving them of sunlight, oxygen, and water – the three things they need to grow.

Below, we show and describe some of the most common purple flower weeds and identify and manage them.
Wild Violet growing at the base of a tree
Wild violet prefers a moist, shady environment; however, mature plants are drought tolerant. This detail means wild violet can originate in an ideal place in your yard (like under a tree or near a shaded downspout) but spread to just about anywhere it wants in one of two different methods.
Creeping Charlie, also known as Ground Ivy, is a broadleaf weed from the mint family. This branching weed grows about one inch high and quickly becomes a low-growing mat of stems and leaves scattered around your yard.
Because wild violets have both seeds and rhizomes, be extra careful to dispose of the pulled waste properly, so regrowth does not occur.
How do I get rid of it?
Because Henbit spreads through seed production, preventing those seeds from forming will greatly assist in controlling this weed.
The following four weeds with purple flowers are probably the most notorious culprits responsible for invading your landscape:
Who doesn’t like pretty purple flowers? In their proper place, purple flowers and the plants that produce them are lovely. However, when they start to over-run your lawn or crowd out the plants in your garden, these purple flowering plants become weeds. To complicate the issue, a number of weeds have purple flowers, so identifying what you’re dealing with in your lawn or garden can be tricky. If you’re asking “What are the weeds with purple flowers called?” I’ve got you. Today I’ll introduce you to the 4 most common weeds with purple-colored flowers and help you understand how to control and eliminate them from your lawn and landscape.
What is it?
It is not generally a weed that will take hold of your actual lawn, so if you have purple flowering weeds in your grass, Henbit probably isn’t what you’re dealing with.
Purple Deadnettle prefers a quite unsavory habitat. It can thrive in moist areas such as drainage ditches, fallow fields, waste areas, and weedy edges of woodlands.
