Mucuna

Family: Papilionaceae
Common Name: Scarlet Jade Vine, New Guinea Creeper

This tropical genus of around 100 species consists of climbing plants or lianes, many native to tropical Asia and the Pacific Islands. Few species are in general cultivation, but those that are have spectacular flowers. The stems of these plants are often covered with irritant hairs. The seeds of some species are used in medicinal drugs, while others are planted as fodder crops.

Species

M. bennettii, a native of New Guinea, is a quick-growing climber which can reach 20 m (65 ft) into the tops of the rainforest canopy in its habitat. It has compound leaves, with elliptic to oval leaflets. Short, dense flower clusters are made up of numerous, bright scarlet, boat-shaped flowers which make a very showy display, mostly during the summer months.

M. pruriens, native to tropical Asia, has become widely naturalized in the tropics. Its stems are covered in rough hairs when young, though these become smooth in time. Its flowers are deep purple or pale lilac to white and may be produced through spring and summer. It is an annual or it may live for a few years.

Cultivation

Outside the tropics and subtropics, these plants need to be grown in a warm greenhouse or conservatory in pots of soil-based potting compost. Provide good light, but shade from direct sun. After flowering, prune side shoots back to within four buds of the main stems. Propagate from seed sown in spring and germinate at 21°C (70°F)
