Yellow Woodsorrel University Links Control Options Germination Dates Matchweed, also called mat lippia, is a mat-forming perennial with opposing leaves on hairy branching stems.
Leaves have small teeth at the outer tip.
The purple to white flowers emerge around the tip of the seed stalk forming a match-head appearance. Matchweed spreads by both seeds and stolons along prostrate stems. Matchweed occurs from the transition zone to the Southern coastal areas and beyond, including Hawaii, Mexico, and Central and South America. Use a selective postemergent herbicide suitable for the turf species infested. For optimum control, make your herbicide application when matchweed is actively growing and in the four leaf to flower stage of growth.
