Cultivation

Requires a very warm sunny position in a moist but well drained soil. Often cultivated for its edible seed in warm temperate and tropical zones, it is best started off in a greenhouse in Britain and planted out after the last expected frosts. Plants have given reasonable yields for the past 3 years on our trial grounds in Cornwall . This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby. When removing plant remains at the end of the growing season, it is best to only remove the aerial parts of the plant, leaving the roots in the ground to decay and release their nitrogen.
