Downy hemp nettle

Galeopsis pubescens, the downy hemp nettle, is an annual herb in the mint family (Lamiaceae) growing 20–50 cm tall. Its four-angled stem is covered with both soft and bristly hairs, with bristles concentrated and often thickened at the nodes. Leaves are opposite, lanceolate to ovate-lanceolate, serrate, hairy, and up to 7 cm long with petioles but no stipules. The two-lipped flowers are scarlet to scarlet-red, 2–2.5 cm long, arranged in whorled cymes at the upper leaf axils; the corolla tube is yellowish, the three-lobed upper lip is spotted, and the lower lip is hairy. Blooming runs from July to September. The species is widely distributed in temperate Europe and western Asia, ranging from eastern France through central Europe to Russia, the Caucasus and Siberia, growing in forest margins, fallow fields and ruderal sites.
