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 >>>

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.

Other Uses

Soil conditioner  Wood

Agroforestry Uses: The tree has an open canopy, fixes atmospheric nitrogen and has soil improvement qualities. It is often left when the forest is cleared, especially to provide shade in tea plantations, and is sometimes also planted in such places[404 , 730 ]. Other Uses: The heartwood is brown, with dark streaks and alternating dark and light coloured concentric bands; the sapwood is white. The wood is very hard and of good quality, but is not used in India[146 ]. The wood is used for construction and making furniture[404 , 730 ]. The wood can be used for fuel[404 ].

Special Uses

Carbon Farming  Nitrogen Fixer

Cultivation details

Agroforestry Services: Nitrogen  Management: Standard  Regional Crop  Staple Crop: Protein

A plant of the tropics, where it is found at elevations up to 700 metres. It grows best in areas where annual daytime temperatures are within the range 20 - 34c, but can tolerate 6 - 42c[418 ]. It prefers a mean annual rainfall in the range 2,000 - 2,400mm, but tolerates 1,100 - 5,000mm[418 ]. Grows best in a sunny position, but tolerates light shade[418 ]. Succeeds in most soils of moderate fertility[418 ]. Prefers a pH in the range 5.5 - 6.5, tolerating 4.5 - 7.5[418 ]. The tree is a host of the lac insect (Laccifer lacca), the female of which secretes the resin 'lac' that was formerly used to make shellac[730 ]. 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[200 ].

Carbon Farming

  • Agroforestry Services: Nitrogen  Plants that contribute to nitrogen fixation include the legume family – Fabaceae.
  • Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
  • Regional Crop  These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.
  • Staple Crop: Protein  (16+ percent protein, 0-15 percent oil). Annuals include beans, chickpeas, lentils, cowpeas, and pigeon peas. Perennials include perennial beans, nuts, leaf protein concentrates, and edible milks.

Propagation

Seed - it has a hard seedcoat and may benefit from scarification before sowing to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing.
