Lamium purpureum, known as red dead-nettle, purple dead-nettle, red henbit, purple archangel, or velikdenche, is a herbaceous flowering plant native to Europe and Asia.
Lamium purpureum grows with square stems to 5ń20 cm (rarely 30 cm) in height. The leaves have fine hairs, are green at the bottom and shade to purplish at the top; they are 2ń4 cm long and broad, with a 1ń2 cm petiole (leaf stalk), and wavy to serrated margins.
The zygomorphic flowers are bright red-purple, with a top hood-like petal, two lower lip petal lobes and minute fang-like lobes between. The corolla shows a line of hairs near the base of the tube. They may be produced throughout the year, including mild weather in winter. This allows bees to gather its nectar for food when few other nectar sources are available. It is also a prominent source of pollen for bees in March/April (in UK), when bees need the pollen as protein to build up their nest.
It is often found alongside Henbit Dead-nettle (Lamium amplexicaule), which is easily mistaken for it since they both have similar looking leaves and similar bright purple flowers; they can be distinguished by the stalked leaves of Red Dead-nettle on the flower stem, compared to the unstalked leaves of Henbit Dead-nettle.
Though superficially similar to species of Urtica (true nettles) in appearance, it is not related and does not sting, hence the name "dead-nettle".
Young plants have edible tops and leaves, used in salads or in stir-fry as a spring vegetable. If finely chopped it can also be used in sauces.
Undyed, the pollen itself is a red colour and is very noticeable on the heads of bees that frequent its flowers.
Frequent in meadows, forest edges, roadsides and gardens.
