Common names

  • Carissa
  • Natal Plum

Native to South Africa, natal plum (scientific name Carissa macrocarpa) is a shrub that belongs to the dogbane or Apocyanceae family. This ripe fruit can be eaten fresh out of hand as well as cooked. Many people take delight in consuming ripe natal plum raw, while there are others who use the fruits to prepare jams, jellies, pied and sauces.

The flavour of natal plum fruits is somewhat akin to the sweet cranberry and its texture is like that of a ripened strawberry. However, there are several people who claim that the fruit tastes like the slightly unripe cherry. Barring the red hued fruits, the entire natal plum tree is poisonous. In fact, only the fruit of this plant is edible. Although the fruit is called natal plum its taste has nothing to do with that of the actual plum.

As the name of the fruit suggests, natal plum is native to South Africa's Natal province. In Africa, plants belonging to the Carissa species are found growing over a vast area extending from Senegal to Sudan and then again from Ethiopia to South Africa. Towards the beginning of the 1900s, this plant was taken to the Philippines. However, this species is not a common sight in South Asia. In fact, a close cousin of natal plum called karonda (scientific name Carissa carandas) has its origin in India and, hence, this species is often seen in the south-east Asian nation.

In present times, is found growing all over the African continent as well as in the warmer areas of the United States, such as Hawaii, California and Florida. A number of people tried to introduce this shrub to Israel, but their attempts proved to be futile.

In fact, it can often be difficult to cultivate natal plum (Carissa macrocarpa) as this plant gives out a milk-like sap when its branches are cut or broken. This actually makes the harvesting and transportation of the red-colored fruits more difficult because the sap may damage the fruits easily. The sap, which clots easily, is also responsible for the short shelf life of the berries. The natal plum is a very important source of nutrition, besides being a major income source for the farmers in Africa who cultivate the shrub. Moreover, this fruit has great potential to do good business in the global market.

The fruits of natal plum are ornamental and plum as well as round. They appear twice in a year – once in summer and again in autumn (fall) soon after the flowering seasons are over. In coastal areas where the temperature is moderate, the plants bear fruits throughout the year.

While the tube is pubescent inside, the lobes are oblong shaped measuring between 0.9 cm and 2.4 cm in length and they are overlying to the left side. Within two years of the germination of the seeds, the plants start producing ovoid-shaped red-colored fruits that measure between 2.5 cm and 7.6 cm. Each fruit contains 16 seeds.

The unripe fruits have a green hue, which changes to vivid red and later to violet when they are ripe. The skin of the fruit is tough and tastes somewhat bitter. The flesh of the fruit is slightly grainy and deep red colored inside. Often the fruit may be crimson-hued with white mottling. The flavour of natal plum is slightly pungent, but they are succulent.
