The Kei Apple (Dovyalis caffra) is a small, thorny shrub or tree native to southern Africa. It produces bright yellow or orange fruits that are tart and juicy, often used in jams and jellies. The fruit is rich in vitamin C, while the dense branches make it a popular choice for hedges. Hardy and drought-tolerant, the Kei Apple thrives in warm climates and can grow in poor soils.
