About
Planchonella australis, also known by the synonym Pouteria australis, is a medium to tall rainforest tree of the family Sapotaceae native to Queensland and New South Wales, Australia. It is known by the common name black apple, wild plum, yellow buttonwood, black plum and yellow bulletwood.
How to grow it
Fast growing and easy to grow, Planchonella australis adapts readily to cultivation, preferring good drainage, as well as moisture, and extra fertilising. It is also tolerant of moderate frosts. It can be used in revegetation projects, and is propagated by seed or cuttings.
Where it grows
The species ranges along the eastern coastline of Australia, from Bulburin in Queensland to the Illawarra region of New South Wales. It grows in various types of rainforest, with specimens on the red basalt soil of the MacPherson Range attaining a large size.
Uses
The fruit of the black apple is edible out-of-hand. It has a sweet and fibrous flesh. However, it is also favoured by maggots, which are often found inside. The taste has been reported as variable. Indigenous Australians in the Gosford region are recorded as traditionally having eaten the seeds. The 1889 book 'The useful native plants of Australia' records "Black Apple" "Brush Apple" or Achras australis as being called "Jerra-wa-wah" in the Illawarra and Brisbane Waters areas of New South Wales. The tree was originally harvested for its timber by colonialists. The attractively yellow-patterned wood is hard and suitable for making rulers.
