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 >>>

A bark decoction is a component of a traditional medicine against leprosy[299 ].

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

Other Uses The heartwood is fairly dark red-brown, turning chestnut brown with age; it is distinctly demarcated from the 5 - 9cm wide band of pale brown sapwood. The grain is usually straight, but sometimes interlocked; the texture fine to medium. The wood is very heavy; very hard; strong; resilient; stiff; very durable, it is rarely attacked by termites, but must be treated to prevent marine borer attack; the sapwood is not susceptible to Lyctus borers. Shrinkage rates are high; drying is slow, with high risks of distortion and checking; the dried wood is fairly stable. The wood is slow and difficult to saw due to the high silica content, which leads to severe blunting, and an irritating dust is produced; it should be sawn as fresh as possible and stellite-tipped sawteeth are recommended; planing is relatively easy and gives a smooth surface; pre-boring for nailing and screwing is recommended to avoid splitting, but the wood holds nails well; it glues well, when done carefully. The wood is considered suitable for heavy construction and flooring, mine props, ship and boat building, vehicle bodies, sporting goods, agricultural implements, musical instruments, precision equipment, joinery, sleepers, poles and piles, toys and novelties, and pattern making. The low saturation point makes the wood suitable for use in humid conditions such as mine work[299 , 848 ]..
