Carissa macrocarpa

Natal Plum
Apocynaceae
Evergreen, Shrubs

Natal plum’s best climates are Zones 22–25, 27, and H2, but so many gardeners find this South African native appealing that it is also grown in Zones 12, 13, 16–21—far beyond safe limits. Fast-growing, strong, upright, rounded shrub of rather loose habit to 5–7 ft. tall and wide (occasionally much larger). Oval, leathery, 3-in. leaves are lustrous rich green. Spines along branches and at end of each twig discourage trespassers.
