Carissa macrocarpa aka Natal Plum

Carissa macrocarpa, also known as Natal plum or large num-num, is a spiny evergreen shrub native to tropical and southern Africa, particularly in the coastal bush of the Eastern Cape and Natal. It is a member of the Dogbane family (Apocynaceae) and is not related to true plums. The plant can grow well in coastal areas and is often used as an ornamental plant, barrier hedge, and for erosion control on mild slopes. The shrub produces shiny, deep green leaves and fragrant white flowers that bloom for months at a time and intensify at night. The showy, edible red fruits appear in summer and fall, and in moderate coastal areas, the fruits can appear throughout the year. The fruit can be eaten raw or used to make pies, jams, jellies, and sauces. Despite claims that the plant is poisonous, the College of Agricultural and Environmental Sciences at the University of California, Davis rates it as mildly toxic. The plant has potential to improve nutrition, boost food security, foster rural development and support sustainable landcare. The most common cultivars sold in nurseries are low shrubs and groundcover plants, both with small thorns. Natal Plum is a versatile and easy-to-grow shrub that adds beauty and functionality to any landscape.
