Motherwort (Leonurus cardiaca)

Easily distinguished from anything similar by the foamy appearance of the flowers, which have puffy tufts of hair on their upper lips. “Motherwort” is so named because it was used by herbalists for what have traditionally been called “female difficulties.” This plant was part of a large stand at the edge of a dense thicket in Beechview, whre it was blooming in the middle of July.

Gray describes the genus and the species:

(Name from leon, a lion, and oura, tail, i.e. Lion’s-tail.)
