The fruit of the carissa is an oblong berry which contains numerous small seeds. The green fruit is poisonous, sometimes dangerously so. The ripe fruit are edible, but may be fairly tart, though some species have fruity flavours with overtones of strawberry or apple. They are rich in Vitamin C, calcium, magnesium and phosphorus. The fruit of C. macrocarpa are especially relished[who?] and eaten raw or used to make jelly. Various birds eat Carissa fruit and distribute the seed.
Water regularly but allow time for these shrubs to dry out a bit between waterings. Although carissa is considered drought-tolerant, getting watered on a regular, well-timed basis will keep this shrub pretty and healthy. 781b155fdc
