Black mulberry + Natal plum

Morus nigra, the black mulberry, is a species of flowering plant in the family Moraceae, native to southwestern Asia, where it has been cultivated for so long that its precise natural range is unknown. The edible fruit is dark purple, almost black, when ripe, 2-3 centimetres (0.8-1.2 in) long, a compound cluster of several small drupes; it is richly flavoured, similar to the red mulberry (Morus rubra) but unlike the more insipid fruit of the white mulberry (Morus alba). Black (Morus nigra) mulberries are thought to have originated in the mountainous areas of Mesopotamia and Persia and are now widespread throughout Afghanistan, Iraq, Iran, India, Pakistan, Syria, and Turkey, where the tree and the fruit are known by the Persian-derived names toot (mulberry) of shahtoot (شاه توت) (king's or "superior" mulberry), or, in Arabic, shajarat tukki. Jams and sherbets are often made from the fruit in this region.

Carissa macrocarpa (Natal Plum), is a shrub native to South Africa, where it is commonly called the Large Num-Num. In Zulu, as well as in the Bantu tribes of Uganda, it is called amatungulu. In Afrikaans the fruit is called Noem-Noem. C. macrocarpa deals well with salt-laden winds, making it a good choice for coastal areas. It is commonly found in the coastal bush of the Eastern Cape and Natal. It produces shiny, deep green leaves and snowy white flowers whose perfumed scent intensifies at night. Like other Carissa species, C. macrocarpa is a spiny, evergreen shrub containing latex. They bloom for months at a time. The ornamental plump, round, crimson fruit appears in summer and fall (autumn) at the same time as the blooms. In moderate, coastal areas the fruits appear through the year. The fruit can be eaten out of hand or made into pies, jams, jellies, and sauces. Some claim that other than the fruit, the plant is poisonous. However this claim is a myth, possibly based on similarities to other plants with milky sap. The California Poison Control System rates the plant as mildly toxic. It appears in the South African National tree list as number 640.3. A traditional food plant in Africa, this little-known fruit has potential to improve nutrition, boost food security, foster rural development and support sustainable landcare.
