Stachys is a genus of about 300 species of annual and perennial herbaceous plants and shrubs in the family Lamiaceae. The distribution of the genus covers Europe, Asia, Africa, Australasia and North America. Common names include Heal-all, self-heal, woundwort, betony, lamb's ears, and hedgenettle. Wood betony, Stachys officianalis, was the most important medicinal herb to the Anglo-Saxons of early medieval Britain.
The stems vary from 50-300 cm tall, with simple, opposite triangular leaves 1-14 cm long with serrated margins; in most species the leaves are softly hairy. The flowers are 1.2 cm long, clustered in the axils of the leaves on the upper part of the stem, the corolla 5-lobed with the top lobe forming a 'hood', varying from white to pink, purple, red or pale yellow.
Stachys species are used as food plants by the larvae of some Lepidoptera species including the Coleophora case-bearers C. auricella (recorded on S. officinalis), C. lineolea and C. wockeella (feeds exclusively on S. officinalis).
Habitat
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.
