Plum Natal Carissa macrocarpa fl bery togThis evergreen shrub has shiny dark green leaves, sharp spines, and fragrant white or pink fragrant flowers that are followed by edible red fruit.  The sweet cranberry flavored fruits are about two inches across and can be eaten raw or used for pies, jellies or preserves.  Originally the shrub was grown for the fruit but more recently cultivars have been developed for ornamental purposes, especially ground covers, with the fruits an attractive and tasty addition.  Native to Natal where it grows along the coast, this shrub is very tolerant of wind, salt spray, and soil salinity so makes an excellent plant for sea side gardens.  It’s substantial thorns make it useful for barrier hedges and its dense green leaves makes it a good screen. Sprawling cultivars make good ground covers.  For those living in colder areas, Natal plum can be grown in a container and taken in doors during the winter. It can also take the wind of a balcony location.  There are many cultivars so check local nurseries for one that suits you needs and wants.
