Young shoots about 7cm long, harvested as the leaves unfurl, have a flavour like asparagus[296 ]. A sweet flavour, rather similar to fresh garden peas[296 ]. The leaves are a good source of protein (about 6 - 10%[298 ]) and are very nutritious[296 ]. Ripe fruits can be made into sweetmeats[301 ]. A green dye, obtained from the leaves, is used for food dyeing[317 , 418 ].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

A plant of the tropics, where it is well adapted to lowland conditions but can also be cultivated at elevations up to 4,000 metres. It grows best in areas where annual daytime temperatures are within the range 26 - 35°c, but can tolerate 5 - 38°c[418 ]. It prefers a mean annual rainfall in the range 900 - 1,200mm, but tolerates 600 - 4,000 mm[418 ]. Succeeds in full sun and semi shade[296 ]. Survives dry conditions and does not require a rich soil[296 ]. Tolerant of very heavy soils[298 ]. Tolerant of heavy rainfall areas, though they prefer a well-drained soil[298 ]. Prefers a pH in the range 6 - 7, tolerating 5.5 - 7.5[418 ]. First harvest may be taken after 55 - 70 days[418 ]. Plants can be harvested throughout the year[418 ]. In Java, the plant flowers all year-round and fruiting is usually abundant[418 ]. Plants are fairly resistant to insect predations[296 ].
