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 >>>

Other Uses

Agroforestry Uses: A natural and important pioneer species within its native range, the tree quickly invades cleared land and fresh clearings in the forest. A short-lived tree, it quickly provides the shelter needed to allow the more permanent forest trees to become established, and then dies off to allow those species the necessary space to grow to full size[694 , K ]. It is used as a pioneer tree in landscape rehabilitation projects[327 ]. Other Uses: A black dye is obtained from the bark and leaves[46 ]. It is used for staining baskets and other items made from rattan and Corypha palms[46 ].
