At mowing time, you may cut the top yellow flower, but it is best to remove all the long root as well.

What are the Purple Weeds Called?

As a lawn weed, purslane produces a high number of seeds. To control it, you will need a chemical control regimen, though both types. A pre-emergent herbicide and also a post-emergent herbicide will be required.

The plants grow up to 2 feet wide, and 2 feet tall; and are as happy in the shade as in the sun. To prevent these, wear gloves to remove them, pulling by hand or remove them with a post-emergence herbicide. (Read Do Roses Need Full Sun)

Bindweed (Convolvulus arvensis)

Creeping Charlie is a perennial and flowers in late spring. The purple flowers are kidney-shaped leaves that are toothed. You find these purple flowering weeds; the grass of your lawn is where they spread and creep where they try to take control in your garden.

Weeds that grow white flowers

Japanese knotweed has small white flowers that bloom from late summer to early fall. The flowers appear in spikes or loose clusters called panicles.

The velvetleaf is a competitive weed for vegetables in your garden. It sucks water and nutrients from the soil, which can compromise the healthy, sustained growth of your plants. This summer annual also contains a chemical that inhibits the germination and growth of your plants. With the germination and growth of your desired vegetation stymied, velvetleaf is then able to establish a dense monoculture in that area.

Herbicides work well for controlling the velvetleaf plants in your lawn or garden. However, it’s recommended that you use a pre-emergent herbicide to prevent it from showing up in the first place. The adaptations this plant has made to increase its chance of survival are harmful to your other plants, and having just one velvetleaf around your healthy plants is too many.

Tall Flowering Weeds

The flowers of the daisy are complex around a thick yellow center. The flowers can be white to pinkish-red and can bloom throughout the entire year. Even in the dead of winter, you might just find a daisy flower.

The flowers of this perennial weed can range from pink to purple and can be found from May through September. The flowers appear at the end of the terminal spikes of the plant’s stem. The flowers will appear in vertical layers growing out from the terminal spike of the stem.

The spear thistle will colonize primarily in undisturbed and uncultivated areas like pastures and roadsides. This can prove to be a problem for those of you with hayfields. These weeds also have a bitter taste that keeps grazing animals from controlling their growth through foraging.


But if one just shows up on your lawn without your permission, then it needs to be dealt with. There are a few easy steps you can take to rid yourself of this beautiful annual plant. Follow these steps:

Common chickweed is a low-growing winter annual weed that germinates in cool, wet weather. Its smooth leaves are elliptical in shape and grow opposite each other. The chickweed grows in a dense mat across the ground that branches out frequently near the base. Branching occurs less frequently the further out you travel from the base of the plant. The leaves are somewhat hairy on the bottom surface and hairless on the top.
