Kei apple is a small invasive tree with apricot-coloured fruit.
Kei apple is a thorny small tree from southern Africa which has become a bushland weed in western Sydney. Its dense foliage can outcompete and shade native plants. It's long sharp thorns are up to 7 cm and can be a safety hazard.
Kei apple is a tree up to 6 m high with sharp thorns, smooth green leaves and apricot-coloured edible fruit.
Kei apple is found in Queensland, New South Wales and South Australia. It can be found in bushland around western Sydney, where it is being controlled.
It is native to southern Africa.
Kei apple prefers full sun and it tolerates frost and drought. It grows well in most soil types, including saline soils but prefers well drained soil.
Plants spread easily by seed. The fruit are eaten by birds and new plants often grow under trees or other places where birds perch.
