Red dead-nettle  (Lamium purpureum)

Evidence of red dead-nettle has been found in Bronze Age deposits, and it seems likely that this plant was introduced to Britain with early agriculture (1). It is a hairy plant that branches from the base. The leaves have wavy to serrated edges and are attached to the stem with a stalk. The flowers are arranged in an inflorescence and are pinkish-purple in colour (2) with a hooded upper lip (4). Red dead-nettles are so-called as they do not sting (5).
