Stachys is a genus of shrubs and annual or perennialherbs. The stems vary from 50–300 cm (20–118 in) tall, with simple, opposite, triangularleaves, 1–14 cm (0.39–5.51 in) long with serrate margins. In most species, the leaves are softly hairy. The flowers are 1 to 2 cm (0.39 to 0.79 in) 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.
In Europe, Stachys can be found growing in wastelands, grasslands and woodland edges. All-heal thrives in any damp soil in full sun or in light shade. Plants are apt to become troublesome weeds in turf that is at all damp. Sow seed in very early spring in a flat outdoors, or give a short cold and moist conditioning treatment before sowing in a warm place. Growing from 1 to 2 feet high, with creeping, self-rooting, tough, square, reddish stems branching at leaf axis. The leaves are lance shaped, serrated and reddish at tip, about an inch long and 1/2 inch broad, grow on short stalks in opposite pairs down the square stem. The flowers grow from a clublike, somewhat square, whirled cluster, immediately below this club are a pair of stalkless leaves standing out on either side like a collar. Flowers are two lipped and tubular, the top lip is a purple hood, and the bottom lip is often white, it has three lobes with the middle lobe being larger and fringed upwardly. Flowers bloom at different times depending on climate and other conditions. Mostly from June to August. Gather whole plant when flowers bloom, dry for later herb use. Leaves and small flowers are edible.
