IdentificationMotherwort is a familiar non-native plant along mountain roadsides and waste places. It is a very distinctive mint, with the leaves divided into 3 sharply pointed lobes, like a very narrow Red Maple (Acer rubrum) leaf; the uppermost leaves are less deeply cut/dissected. Pale pink flowers may grow in small groups in the axils, from below mid-stem all the way to the top of the stem.
