Stachys is a genus of shrubs and annual or perennial herbs. The stems vary from 50–300 cm tall, with simple, opposite, triangular leaves, 1–14 cm long with serrate margins. In most species, the leaves are softly hairy. The flowers are 1 to 2 cm long, clustered in the axils of the leaves on the upper part of the stem. The corolla is 5-lobed with the top lobe forming a 'hood', varying from white to pink, purple, red or pale yellow.
