Description

Sericea lespedeza (Lespedeza cuneata) is a perennial weed that is commonly found in pasture areas. The woody stems grow upright. Individual leaves are oblong in shape, and appear to have been folded. Small white and purple flowers can be found in the axils of the leaves. An important identifying characteristic of sericea lespedeza is the stiff hairs that can be found on the stem.

Cultural Control

Perennial broadleaf turf weeds are capable of living more than two years. They thrive in weak, thin turf; golf fairways and roughs; home lawns; playfields; and industrial grounds. Proper turf maintenance is the key to control of this weed. First, select adapted turfgrass cultivars for your area and then properly fertilize, mow, and water to encourage dense growth.
