Description

Common winter annual weed in turf. Distinct purple bilaterally symmetrical tubular flower. In the mint family, so similar to other mints such as purple deadnettle and ground ivy. Purple deadnettle has downturned leaves with longer leaf stems (petiole). Ground ivy has a prostrate growth habit and flowers are pinkish and less conspicuous. Often given as a flower on Mother’s Day from 5 year olds who like the purple flower and do not know any better that it is a weed.
