Latin Name:  Arisaema costatum
Family:  Araceae
Author:  (Wallich.)Mart.

Known Hazards:  The plant contains calcium oxylate crystals. These cause an extremely unpleasant sensation similar to needles being stuck into the mouth and tongue if they are eaten but they are easily neutralized by thoroughly drying or cooking the plant or by steeping it in water.

Mature Height:  0.6   Mature Width:  0.4

Habitat:  Wet cool woodlands and cliffs, often forming large colonies. Shrubberies, 2000 - 2600 metres[51].

Cultivation Notes: Prefers a cool peaty soil in the bog, woodland garden or a sheltered border in semi-shade[200]. Prefers a loamy or peaty soil[1] and will tolerate a sunny position if the soil is moist but not water-logged and the position is not too exposed[1, 200]. Plants are nearly hardy in Britain, they normally succeed outdoors in the milder areas of the country[1]. Tubers should be planted about 15cm deep[233]. Only plant out full sized tubers and mulch them with organic matter in the winter[200]. Plants multiply quickly once they are established[200]. Plants need protection from slugs[200]. This species has very large leaves, to 40cm long[200]. Most species in this genus are dioecious, but they are sometimes monoecious and can also change sex from year to year.
