21 Types Of Flowering Weeds

Of all the different types of weeds, flowering weeds are sometimes the most pleasant to find in your garden.

But if they’re growing where they’re not wanted, they’re still weeds. And you’ll probably want to remove them.

But before you start, identification is important. Why?

Because then you can use the right method for successfully getting rid of the weeds before they spread.

So in this list, I’ll show you some of the most common types of flowering weeds and help you identify them.

Let’s dive in!

Henbit (Lamium amplexicaule)


This winter annual weed produces reddish-purple flowers in the spring. With the flowers that grow in the upper leaves appearing in a whorl.

The weed has a square stem and usually grows up to 12-inches tall. The leaves grow opposite each other around the stem, and have scalloped edges and prominent veins on the undersides.

It’s rare to find henbit in healthy lawns. It likes to invade areas of thin and patchy turf. Especially in shady areas with moist soil. So good lawn care practices can keep this weed out. And if it’s already growing, it’s easy to take care of with a post-emergent herbicide.

Dandelions (Taraxacum)


Dandelions are one of the most recognizable flowering weeds. You’ll often notice dandelion weeds growing on your lawn when they bloom in the spring, producing their distinctive yellow flowerheads. The flower eventually gives way to a fluffy seed head with the seeds dispersed by the wind.

Cutting them down before the seed head appears helps to stop dandelions from spreading around your yard. But getting rid of dandelion weeds can be tricky. They have a thick taproot that grows deep into the soil. And to stop this flowering weed from growing back the taproot will have to be fully removed or killed.

Speedwell (Veronica)


Also called Veronica, speedwell is a common flowering weed. It stands out due to its numerous small flowers that can be blue, white, pink, or purple depending on the variety. The weed also has many small lobed leaves with scalloped edges that grow in pairs.

If left unchecked, speedwell can quickly get out of hand, taking over your lawn. Keeping a healthy lawn can stop the spread of speedwell. And chopping the heads off the flowers before they bloom also helps with control. If necessary, you can use pre-emergent herbicides in the spring to prevent seed germination.

Wild Roses (Rosa sp.)

Wild Roses

You can find wild roses growing throughout North America. These pretty weeds with pink flowers spread easily, and you’ll see them in woodlands, pastures, and meadows, as well as your yard. Wild roses bloom between May and August, depending on the species. They produce flowers with 5 petals that can be white as well as pink.

Some people like wild roses for the attractive wildflower they undoubtedly are. But other people consider them weeds. If you choose to plant them in your garden you need to take care of them because containment can be difficult and they can quickly take over an area.

You can then make the adjustments necessary to encourage desirable plants to grow.

Orange Jewelweed (Impatiens capensis)

Orange Jewelweed

Orange jewelweed is a summer annual weed that’s native to North America. It’s common to see orange jewelweed growing in ditches, bottomland soils, and wetlands, as well as alongside creeks.

The plant produces clusters of 1-3 orange flowers that grow from the leaf axils of the upper leaves. The leaves are thin-textured, ovate, and hairless. And they grow alternately on slender petioles from round, succulent, pale-green stems.

When the plant is bathed in sunlight, the orange flowers glisten. Giving rise to the name Jewelweed.

The weed grows from 2-5 feet tall. And it has a shallow root system, so you can easily remove it by hand pulling. Just make sure you get rid of all of the roots to prevent the plant from regrowing.

Field Bindweed (Convolvulus arvensis)

Field Bindweed

Field bindweed is a perennial broadleaf weed that’s sometimes called morning glory because of the similarity of its bell-shaped, white flowers.

Creeping Jenny (Lysimachia nummularia)

Creeping Jenny

Also called moneywort, creeping jenny is a tenacious weed. It spreads along the ground by creeping stems known as stolons. Strangling and crowding out plants that get in its way.

The stolons root where the nodes touch the ground. And the weed also spreads by seed. And it can be difficult to get rid of once it becomes established.

In the summer, creeping jenny is a flowering weed. Producing small yellow flowers. And you can also identify this weed by its bright green leaves. The leaves are scalloped edged and round or kidney-shaped.

Creeping jenny likes to grow in moist and shady areas, So you can control this weed by changing the conditions. Water less frequently. And prune back trees and hedges to allow more light to reach the ground.

Creeping jenny has deep roots, so it’s a hard weed to get rid of. But repeated pulling of the plant before it flowers eventually exhausts the roots. You can also repeatedly apply chemical herbicides to kill the roots.

Purple Leaf Japanese Honeysuckle (Lonicera japonica ‘Purpurea’)

Purple Leaf Japanese Honeysuckle

Purple leaf Japanese honeysuckle is a sprawling vine that grows fast. It quickly covers outbuildings, walls, and other obstacles that get in its way. The weed also forms a thick ground cover when unsupported.

The flowers look beautiful. But if you have children it’s safer to remove this dangerous weed from your yard.

Oxalis (Oxalis corniculata)


It’s easy to mistake oxalis leaves for clover. The light green leaves each consist of 3 or 4 leaflets. But you can identify this weed by its small, cup-shaped yellow flowers that appear in the summer and fall.

Oxalis grows in both sunny and shady areas of your garden. And you can use mulch in the spring to prevent the weed from becoming established. To get rid of weeds that are already growing, you can pull oxalis by hand. Or use a broadleaf herbicide.

White Clover ( Trifolium repens)

It’s common to find white clover growing in your garden. You can identify this broadleaf weed by its white flowers. Each flower consists of tear-shaped leaflets clustered around a green center.

Clover is a low-growing plant, typically reaching up to 3-inches tall. As the weed creeps across your lawn, it develops roots from every stem node that contacts the soil.

Wild Violets (Viola sororia)

Wild violet

Wild violets are common garden weeds that bloom between April and June, producing pretty purple-blue flowers. Although some people consider them attractive wildflowers, they quickly spread through your grass and take over if you leave them.

Wild violets are difficult to control. And you’ll often need to use multiple applications of broadleaf weed killer. Applying the herbicide in spring will take care of the first violets that emerge. But more plants will sprout from the rhizomes up until early fall. So more applications are usually necessary to control this weed.

Goldenrod (Solidago sp.)


Some people view goldenrod as an attractive wildflower. While others consider it an invasive weed. In the US you can find between 60-70 species of goldenrod. This flowering weed is often seen in meadows, fields, woodland, and alongside roads.

Black nightshade is a broadleaf annual weed with small white flowers that grow in clusters. Leaves grow alternately from the stems on short stalks.

This is a weed with juicy black berries, but make sure you don’t eat them as all parts of black nightshade are poisonous.

You’ll often find black nightshade growing in areas of rich soil. Which might include your lawn and garden. But you’re also likely to see it along roadsides and river banks, as well as areas where the soil is disturbed such as cultivated land.

Common Evening Primrose (Oenothera biennis)

Common evening primrose

Common evening primrose is a biennial flowering weed. In the first year, the plant forms a rosette of leaves. And in the second year, it sends up a long stem with large alternate leaves and a panicle of pale yellow flowers at the top.
