What are the weeds with purple flowers called?

There are various types of weeds with purple flowers, including musk thistle and Canada thistle. However, the most common purple-flowered weeds are the ones outlined here: wild violet, henbit, creeping charlie, and purple deadnettle. Other common weed types might feature white flowers (like white clover) or yellow flowers.

Wild Violet

Cheerful and sweet with their small purple blooms, delicate stems, and waxy green leaves, wild violets are pretty little plants, but beware; these perennial weeds can overtake your lawn. As far as lawn weeds go, wild violets are extremely aggressive, spreading via their rhizomes. Moreover, they have the ability to self-pollinate.

While some people enjoy allowing wild violets to grow on their property, others with more formally maintained lawns will want to prevent their growth. If you like the look of wild violets and their purple flowers, it’s better to plant their cousins–violas, and pansies–in your flower beds or flower boxes instead. These annuals have purple flowers but are not aggressive like weeds.

How to Get Rid of and Prevent Wild Violet

Broadleaf herbicides are the most effective method for eradicating wild violets and many other perennial weed types from your lawn or garden.

Some gardeners prefer hand pulling weeds, but this is a more labor-intensive method; especially when long stems and extensive weed roots are involved; plus, if any of the plant remains in the soil, its rhizomes could resprout, resulting in the wild violet return.

You can prevent wild violets and their purple flowers from invading your lawn by keeping it lush and healthy. Lawn weeds find it more difficult to invade a thick, healthy lawn. To keep common weeds like wild violets out of your flower beds, be sure to mulch them. The mulch makes it difficult for weeds to emerge.

Creeping Charlie

Creeping Charlie, also known as ground ivy or creeping jenny, is a member of the mint family and is a perennial weed with purple flowers. Creeping charlie like many broadleaf weeds poses a triple threat to lawns and gardens because it spreads via seeds, creeping stems, and rhizomes.

Creeping charlie like many weeds thrives in moist soil, especially near trees and shrubs. By late spring, creeping charlie produces small purple flowers.

Broadleaf herbicides work best. Maintaining the health of your turfgrass is the best defense against lawn weeds like creeping charlie. If creeping charlie invades garden beds, you’ll want to avoid the use of a broadleaf weed killer and stick to pulling the weeds by hand or hoeing.

Henbit is an annual weed that blooms in early spring. It features small purple flowers and green heart-shaped leaves. In addition to sprouting up uninvited on lawns, henbit may frequently be seen growing in fields, drainage ditches, or on roadsides.

Henbit’s seed production is immense–nearly 2,000 seeds per plant. Its seed heads disperse the seeds, ensuring the plant’s propagation. It’s best to eliminate these weeds before seed production takes place.

How to Get Rid of and Prevent Henbit

To prevent henbit and its purple flowers from blooming, maintain a lush lawn. Good drainage is essential as henbit, like many weeds, prefers moist soil.
