natal-plum: Carissa macrocarpa (Gentianales: Apocynaceae): Invasive Plant Atlas of the United States.
This shrub has a moderate to fast growth rate and is best planted (or transplanted) in fall or winter. It will take about two years for the shrub to mature enough to produce harvestable fruits.
The shrubs need afternoon shade in well-drained soil. Avoid growing Carissa shrubs near walkways and outdoor seating, where they can cause injuries with their thick, forked thorns. You should also keep it away from areas where children play because all parts of the plant, except the fully ripe berries, are poisonous.. . . . .364011235251!]0000000000000009783314147482!]
