Some people may be inclined to overlook the presence of a weed with purple blooms if it has found its way into their lawn or garden. Unfortunately, many blooming weeds that seem harmless may cause serious problems.

Likewise, not every weed responds the same way to treatment. For all of these reasons, verifiable identification is crucial.

But even the most seasoned gardeners may not name every weed they see. The good news is that the color of a weed’s blooms is a reliable indicator of whether or not it is a toxic species.

Top 10 Weeds With Purple Flowers

Learn our tried-and-true methods for recognizing and eliminating some of the most prevalent weeds with purple blossoms in the paragraphs below.

1. Henbit

The mint family contains henbit, sometimes confused with Purple Dead Nettle due to its similar look. Like Purple Dead Nettle, Henbit grows in sunny, damp areas and may be seen growing around the edges of ponds and gardens.

Because of its similar qualities, it is challenging to distinguish it from its close sibling in the mint family. Henbit is a creeping plant with a square stem with purple blossoms.

Still, its leaves are rounded and scalloped at the margins, growing slowly and droopily over the ground. The flowers of this plant are often more purple than those of Purple Dead Nettle.

Although henbit is good for pollinators when left alone, it can quickly grow over your yard, suffocating your grass or other plants.

Using a pre-emergent insecticide in the spring and physically removing any Henbit that blossoms may help prevent the weed from spreading across your yard.

2. Wild Violet

Wild violet plants have tiny, fragrant blossoms on short stalks and shiny green leaves. They may also self-pollinate. Rhizomatous weeds are notoriously tough to eradicate.

You should maintain your grass in excellent shape if you want to avoid weeds taking over.

Some people like the look of wild violets in their yards, while others would prefer not to have them.

Depending on the sort of wild violet you have on hand, you may need to adapt the recipe accordingly.

In any case, they spread throughout your yard through underground stems called rhizomes. Plants with thick rhizomes tend to colonize new areas swiftly. That makes them challenging to interact with at times.

3. Purple Deadnettle

Like the ordinary deadnettle, the more vigorous Purple Deadnettle blooms in the spring. It continues to blossom throughout the late spring and summer.

Purple deadnettle has a square stem and triangular, purplish-colored leaves that are a deep purple.

Purple Deadnettle’s invasive weeds have purple flowers, but the plant itself is toxic. They are immune to the weather, pests, and disease.

As a result, weeds may develop quickly, especially in moist areas like drainage ditches.

4. Ground Ivy

Ground Ivy spreads its leaves and branches to form a low carpet over a garden or grass, growing to a height of approximately an inch.

Ground Ivy is distinguished by its serrated leaves and clusters of spectacular, purple tubular blossoms and low, creeping branches. While Ground Ivy may attract helpful pollinators, it also offers major ecological problems.

Because of its persistence and powerful development, leaving it alone will result in its fast proliferation, choking natural vegetation and depriving it of nutrients and water. Mulching and feeding your plants in the spring will help prevent this, as can hand-weeding any weed-infested areas.

5. Forget Me Nots

These gorgeous purple blooms are known as Forget-Me-Nots. Although it is a weed, its striking blue flowers with yellow centers distinguish it from the less common purple blossoms.

Gardeners use this hazardous weed as a border plant because it is lovely and takes little maintenance. Forget-me-nots may be eaten and provide an excellent taste to salads and beverages. They may be canned and used to decorate baked items.

They may behave erratically, spreading over your good grass and sucking nutrients from other plants.

Despite this, they have lovely flowers and are simple to grow without depending on nutrients from other plants. Deadhead the blossoms to prevent the seeds from germinating.

6. Black Nightshade

Black nightshade only survives the summer before succumbing to the cold of October because it is an annual. This weed can grow tall and green, making it a competitor for light with other plants. Furthermore, they may be identified by the clusters of purple and white berries they produce.

In colder weather, the stem of this plant becomes a bluish-purple tint, adding to the plant’s uniqueness. These weeds like rich soil and full sun, although they may also thrive in partial shade.

They can grow into a bushy plant or a climbing vine. Hand-pulling is an efficient weed control approach for this weed. A well-kept garden is shielded from black nightshade by mulch.

7. Creeping Thistle

The first kind of thistle addressed in this article is the Canada thistle, often known as the creeping thistle.

Canada thistle is a notoriously tricky invasive plant to eliminate. It’s a perennial plant with spear-shaped spine-tipped leaves. This weed plant has purple pom-pom-shaped blooms growing in bunches towards the top.

As these weeds develop to seed, their flowers become white and fluffy. Raising soil fertility improves your chances of removing Canadian thistles, favoring low-fertility soil.

It has the added benefit of stimulating the growth of attractive plants. To dismiss them, mow the area regularly and pull them by the roots. Canada thistles are challenging to eliminate due to their deep, fibrous root structure.

8. Musk Thistle

Musk thistle, often known as nodding thistle, is another kind featured in this list. The plant gets its name from its unique downward-sloping flower heads.

The leaves, which may grow to be 15 inches long, are a solid way to identify these plants. Sharp barbs adorn the curving, undulating leaf edges. The stems grow spiny wings. Musk thistle flowers are purple or pinkish.

Musk thistles are ubiquitous roadside weeds, even though they thrive in many areas of the United States with rich, nutritious soil. Flower clusters are typically 2 to 3 inches across.

Musk thistles may grow up to 6 feet tall when ripe. If you allow these weeds to take root in your garden, they will spread quickly and become difficult to eliminate.

9. Common Thistle

Common thistle, also known as spear thistle or bull thistle, is the final kind of thistle we’ll discuss. The fluffy pink or purple blooms on top of a spiny ball are a telltale sign that you’re looking at a common thistle.

Barbs cover the leaves and stems of many plants. The blooming season lasts from June through October.

To stop the weed from flowering, you must mow it as much as possible. You can always try removing the plants manually if you need help. Flowers may spread their seeds via wind.

Therefore, keeping them under control is essential. It’s fascinating to learn that goldfinches and several species of butterflies frequent this weed. It would help if you still got rid of them as quickly as possible since they may quickly spread and take over your landscape.

10. Bill of the Dove’s-Foot Crane

The purple blooms of the dove’s-foot crane’s-bill are easily recognizable due to their jagged petal edges. Some gardeners could even mistake this weed for a beautiful purple ornamental flower due to its attractive appearance.

Rounded and hairy, the leaves have only around 5 or 7 lobes. Therefore we must be cautious. This weed may still spread despite our best efforts. Since it thrives in dry circumstances, this weed may not create too much trouble for your lawn.

You may be able to pluck these plants out of your garden if there are just a few. Keeping your grass well-kept, wet, and nutrient-rich is a smart strategy to discourage the growth of this weed.


What do you name those purple weeds?

It’s either henbit (Teucrium henbit) or purple deadnettle (Lamium purpureum) (Lamium amplexicaule). The similar appearance of these weeds leads to frequent confusion. Like other members of the mint family, these two winter annuals feature square stems, an upright growth habit, opposing leaves, and purple or pink blooms.

How can I eradicate the weeds with the purple flowers?

Struggle with the purple blossoms of deadnettle before they produce seeds. Purple deadnettle, like many other types of mint, spreads rapidly. Applying a post-emergent weed pesticide to your lawn before purple deadnettle and related weeds take over is your best bet for getting rid of these unwanted visitors.

Can you become sick by touching pokeweed?

We don’t know how much pokeweed is safe for humans. Pokeweed is very poisonous and may be fatal if consumed in raw form. Pokeweed may create a terrible blistering rash if you come into contact with its leaves, roots, or berries.

Which weeds are often purple and found in fields?

The most common causes of purple spots in fields are Henbit and purple deadnettle. Both spread quickly and may form dense mats when they reach maturity.

Does Creeping Charlie have purple blossoms?

Small, funnel-shaped, bluish-purple blooms appear in the spring. This plant has a distinct, minty scent when crushed. As a shade-loving plant, Creeping Charlie prefers damp, shady areas like those found beneath trees and bushes. Preventing this plant from growing will be simpler if you can improve the current circumstances.


You should now be familiar with the several weeds that sport purple blossoms and their distinctive appearance. The flowers are lovely, but it’s important to recognize when these plants are really valuable.

Be certain of what you’re planting in your garden’s patches, and take special care to ensure everything is flourishing. Knowing what you’re working with is crucial for creating a functional and aesthetically beautiful landscape, which is why proper identification is vital.
