Here is a useful resource I came across the other day, added to the site for “the benefit of gardeners.” It is a searchable database of plants used by the Ethekwini Municipality’s Urban Design Team. See details HERE.
While this might have a particularly Durban flavour (and the database is limited), I think the information is relevant to all South Africans who want to know a little more about indigenous plants and those endemic to the KZN area. You can search in a number of ways including by common and genus names, fruiting time, flowering time and flower colour, which is helpful to those with limited knowledge (eg. colour and time of flower) of the plants they are looking at. Try it out!
