Natal plum (Carissa macrocarpa) is a shrub from family Apocynaceae. Natal plum is a dense, spiny evergreen shrub or small tree up to 6 m in height. The dark glossy green leaves are ovate, 2.5-7.6 cm long. The white flowers are about 5 cm across and sweetly fragrant, like orange blossoms, especially at night. The edible fruit is a pretty plum shaped red berry about 5 cm long which tastes like sweet cranberries. Natal plum blooms almost all year long and most of the time both flowers and fruit are present. This plant responds well to close pruning and is easily kept at any size. Natal plum does best and produces the most flowers when positioned in full sun, but it tolerates partial shade and it is drought tolerant.
The species may be grown from seed. Natal plum is the perfect hedge plant. Its dense foliage makes it a good screen, and its thorns make it an effective barrier as well. Add on the deliciously fragrant blossoms and edible fruits, and it's hard to think of a better shrub for the tropical garden.
All parts of Natal plum are poisonous except for the ripe fruits. Even the seeds within the fruits are said to be poisonous. The fruits are made into jellies and preserves.
