Description
Lawn burweed is a low-growing winter annual weed that grows in bunches or clumps. It has oppositely arranged leaves that are divided in threes and can be easily confused with parsley-piert (Aphanes macrocarpa (Boiss. & Reut.) Rothm.) but can be distinguished by close examination of the leaves. Lawn burweed, unlike parsley-piert, produces sharp spines in the leaf axils during the spring months that can get caught on shoes, pets, etc. and are often painful if stepped on.
