Uapaca sansibarica is an evergreen African tree in the family Phyllanthaceae. It occurs in deciduous and coastal woodland, wooded grassland, evergreen bushland and riverine woodland at elevations of 500–1,830 m.[1]
Description[edit | edit source]
The tree forms a dense, rounded crown and is recorded at 4–25 m tall. Occasional stilt roots are present. Fruits occur in clusters, mainly on old wood, and are described as brownish-yellow and about the size of a plum.[1]
Taxonomically, Uapaca sansibarica is placed in the genus Uapaca, family Phyllanthaceae and order Malpighiales.[2][3][4] Plants are dioecious, so the sexes are separate.[1]
Cultivation[edit | edit source]
Soil and water[edit | edit source]
The species is associated with both woodland and riverine woodland, as well as wooded grassland and evergreen bushland, across a broad elevation range.[1] A practical cultivation starting point is a deep, organic, well-drained medium that can be kept evenly moist without remaining stagnant. Riverine habitat alone should not be treated as proof of tolerance for permanently waterlogged roots. Occasional stilt roots are recorded, but they do not by themselves justify planting in permanently waterlogged soil.
Sun and humidity[edit | edit source]
Its evergreen habit and occurrence in coastal, evergreen and riverine woodland indicate a warm growing environment with reliable atmospheric moisture. Filtered light is a cautious starting position for young trees, with stronger exposure introduced only as the plant acclimates. Treat hardiness and full-sun performance as site questions rather than fixed species limits.
Seasonal changes[edit | edit source]
Because the tree is evergreen, it should not be managed as a predictably deciduous species. Adjust irrigation to rainfall and temperature rather than imposing a dry dormancy. Fruit clusters are reported mainly on old wood, so heavy routine removal of mature branches could reduce future fruiting wood.[1]
Propagation[edit | edit source]
The species is dioecious, and a planting intended to produce fruit should allow for separate male and female plants rather than assuming that one seedling can provide both sexes.[1] Fresh seed is best sown as soon as it is ripe.[1] Keep the seed fresh between collection and sowing; a germination percentage and fixed schedule should not be assumed from the available guidance.
Flowering, fruiting, and harvest[edit | edit source]
Fruits are produced in clusters, mainly on old wood, and are about plum-sized. The species is dioecious, so sex expression matters when planning a fruiting group.[1]
Fruit should be allowed to become fully ripe. Fully ripe fruit is described as sweet and suitable for making a pleasant juice, whereas fruit that is even slightly unripe is astringent.[1]
Fruit and uses[edit | edit source]
Fully ripe fruit has a sweet flavour and can be used to make juice.[1] The strong astringency of slightly unripe fruit makes harvest timing important. No broader food-safety or medicinal-use claim is made here.
