Lamium album barbatum

Description

L. album is an herbaceous perennial plant growing to 50–100 cm (20–39 in) tall, with green, four-angled stems. The leaves are 3–8 cm (1.2–3.1 in) long and 2–5 cm (0.79–1.97 in) broad, triangular with a rounded base, softly hairy, and with a serrated margin and a petiole up to 5 cm (2.0 in) long; like many other members of the Lamiaceae, they appear superficially similar to those of the Stinging nettle (Urtica dioica) but do not sting, hence the common name "dead-nettle". The flowers are white, produced in whorls ('verticillasters') on the upper part of the stem, the individual flowers 1.5–2.5 cm (0.59–0.98 in) long. The flowers are visited by many types of insects, but mostly by bees.
