FEATURES: Erect winter annual. Square stem with opposite clasping leaf at nodes. Leaves opposite, oval to
ovate in shape with a cordate base and broadly acute leaf tip with netted venation. Lower leaves
can be stalked or clasping, but upper leaves are definitely clasping to the stem almost appearing
as if leaves are joined encircling the stem. Very distinct purple flowers, small, tubular, occurring in
nodes at the apex of the plant. Plant is primarily glabrous which can distinguish it from other mints.
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.
