Urtica dioica L.
Urticaceae (Nettle Family)
USDA Symbol: urdi
A 4-angled stem, covered with many bristly, stinging hairs, has slender, branching, feathery clusters of minute greenish flowers in the leaf axils. Flowers are unisexual, with either male or female on a given plant, or on same plant with males in upper leaf axils, females lower.
Highly irritating to the skin, this Nettle should not be handled. However, the very young shoots and top leaves may be cooked and served as greens or used in soups and stews. The family and genus names come from the Latin uro (I burn).
