Physiognomy: Ad P-Forb

A Eurasian species, which can be cultivated as a ground cover but is too aggressive for most uses, escaping to cover more ground than desired. Now a pernicious weed of lawns, roadsides, river and stream banks, shores, borders of forests and thickets, barnyards, and all sorts of disturbed ground. The earliest Michigan collections seem to be from Ann Arbor (Washtenaw Co.) in 1870 and Port Huron (St. Clair Co.) in 1888, where C. K. Dodge noted that the species was “Becoming very common everywhere. A bad lawn weed.”

Variable in flower size (9–20 mm long) and also in stature, with low creeping plants rooting at the nodes and hence almost impossible to exterminate in lawns, or with tall luxuriant stems in dense taller vegetation along ditches.

Sometimes confused with Lamium, but easily distinguished by the distinctly pedicellate flowers (as well as the strongly 15-nerved calyx).
