Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Summary

Vigna unguiculata subsp. unguiculata, or commonly known as Black-Eyed Pea, is a subspecies of cowpea often cultivated for its edible seeds. It is an annual climbing plant growing up to 4 m in length with straight firm pods. The leaves have three leaflets. Flowers which are white, yellow or blue and large occur often in pairs on the end of long flowering shoots. The seeds are white with a black/dark spot. Being a legume, it has a capability to fix atmospheric nitrogen and functions as a green manure. The seeds are cooked. Immature seeds are used as a vegetable while mature seeds are added to soups and stews or ground into a powder. The seeds can also be sprouted then eaten raw or cooked. Roasted seeds are grounded into a powder and used like coffee. Immature seedpods are eaten raw or cooked. Leaves are cooked like spinach. Crushed leaves are used in a poultice for broken bones.

Edible Uses:

Seed - cooked[46 ]. They can be eaten whilst still green or allowed to dry[46 ]. The immature seeds are used as a vegetable - they can be steamed, boiled, stir-fried etc[301 ]. Mature seeds are added to soups and stews, ground into a powder and used with cereal flour for making cakes, bread etc, or fermented into dosa[301 ]. The seeds can also be sprouted and then eaten raw or cooked in stir-fries etc[301 ]. The roasted seed can be ground into a powder and used like coffee[301 ]. Immature seedpods - raw or cooked[46 , 301 ]. Leaves - cooked like spinach[301 ].

Medicinal Uses

The crushed leaves are used in a poultice to heal and bond broken bones[348 ].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Cultivation details

A plant of the lowland tropics, where it can also be cultivated at elevations up to 1,500 metres. It grows best in areas where annual daytime temperatures are within the range 20 - 35°c, but can tolerate 10 - 40°c[418 ]. The plant cannot tolerate frost It prefers a mean annual rainfall in the range 600 - 1,500mm, but tolerates 400 - 4,100mm[418 ]. Prefers a position in full sun, tolerating light shade[418 ]. Succeeds in a wide variety of soils, from sandy loams to clays, so long as they are well-drained[300 ]. Prefers a pH in the range 5.5 - 7.5, tolerating 4.3 - 8.8[418 ]. Good yields have been obtained on peaty soils, but the plant dislikes alkaline soils since this reduces nodulation of bacteria on the roots and causes chlorosis of the leaves[300 ]. Young seed pods can be harvested about 2 months after sowing, whilst mature seeds can be obtained in 3 - 5 months[300 ]. Up to 6 tonnes per hectare of pods can be obtained per hectare, or 400 - 750kg of dried seed[300 ]. There are many named varieties[300 , 301 ]. Most cultivars are day-length neutral, though short-day forms are also known[300 ]. 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[755 ]. 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.
