About plant names...

Red dead nettle is common but inconspicuous, appearing in fields and weedy places, popping up in gardens. The name “dead nettle” came about because the leaves resemble those of the nettle family, with stinging hairs, but this species is harmless.

Identification: Plants are 4-16" (10-40 cm) high, and somewhat hairy. Stems are 4-angled and glabrous. Leaves are toothed, round or kidney-shaped, deeply and irregularly veined, and ¼-1¼" (6.3-31 mm). Each stem node has two opposite leaves, and each succeeded pair is rotated 90° from the last. Upper, younger leaves often have a red-violet tinge. Flowers are ¼-¾" (6.3-19 mm), appearing from Mar to Oct. They are pink to red to purple in color.

Edibility: Young leaves may be eaten raw or cooked.
