Sichuan Aconite

This genus consists of about 100 species of tuberous perennials that are found throughout northern temperate regions, in woods, thickets, rich grassland, and near water. Monkshoods make handsome border plants, with attractive spring foliage and delphinium-like flowers. The characteristic hooded shape of the flowers allows pollination only by bees. According to Greek myth, A. napellus was created by Hecate, goddess of the underworld, from the foaming mouths of Cerebus, the three-headed dog that guards the gates of Hell. All aconitums contain the alkaloid aconitine, which is one of the most toxic plant compounds known. Aconitum ferox is regarded as the most deadly, followed by A. napellus, which is one of the most poisonous species in the European flora. Monkshoods were used in making arrow poisons, and a number of species are used medicinally in various parts of the world, having therapeutic effects when used correctly by trained practitioners. Aconitum carmichaelii was first mentioned in Chinese medical literature c.CE200. It has two names in Chinese medicine: wu tu refers to the fresh root and fu zi to the root cooked with salt and sugar. The cooking process makes it safer for internal use. Research has found it to be effective in congestive heart failure.

Tuberous perennial with glossy, dark green, deeply cut leaves, to 15cm (6in) across. Dense panicles of large, deep purple-blue, hooded flowers appear in late summer and early autumn.
