Common Missouri Lawn Weeds

Missouri has many different classifications of common weeds such as annual broadleaf weeds, perennial broadleaf weeds, annual grass weeds and perennial grass weeds. Each classification has many different varieties of weeds that a homeowner can find growing in their lawn. Although there are over 30 different weed types--and numerous varieties--some are more common in the lawns across the state than others, according to the University of Missouri Extension.

Annual Broadleaf Weeds

The summer annual broadleaf weeds include black medic, carpetweed and ragweed. The winter annual broadleaf weeds include shepherd's purse and henbit. Black medic has black pods, long stems and yellow flowers. Ragweed produces pollen and can reach a height of several inches with grayish silvery leaves. Carpetweed grows closer to the ground and has oval leaves and white flowers. Henbit has rounder green leaves with small purple flowers. Shepherd's purse has pods shaped like a triangular purse.

Perennial Broadleaf Weeds

Perennial broadleaf weeds that grow in lawns in Missouri include ground ivy, dandelions and bindweed. Bindweed is a creeping vine that has little white flowers and arrow shaped leaves. The dandelion is a long-stemmed weed with a yellow flower and the ground ivy grows over the ground in vines with round, lobed leaves. The joints in the vines root in the soil to spread the weed.

Annual Grass Weeds

Summer annual grass weeds include barnyard grass, goose grass and crabgrass. Bluegrass is the state's winter annual grass weed. Barnyard grass has smooth light green leaves that grow to 4 inches high. Goose grass grows in clumps with folded leaves. Crabgrass has a long, brownish stem, spreads along the ground and has blade-like leaves with tiny hairs on both sides.

Perennial Grass Weeds

Perennial grass weeds in Missouri include quackgrass and nimbleweed. Quackgrass spreads over the lawn through the underground roots and stems. Nimbleweed is a brown weed that has thin leaves spread apart from each other on the stem. In a green lawn, the nimbleweed stands out because of its brown coloring.
