Agapanthus africanus is said to be difficult to cultivate (unlike A. praecox). It does not survive freezing temperatures, which prevents it from growing higher than about 1000 m above sea level. It flowers particularly well after fynbos fires and survives the fires comparatively easily due to the fleshy core at the base and the root system.
The more well-known relative, A. praecox, which is the common garden species with so many artificially created offspring in the form of horticultural cultivars, also has three natural subspecies. They are found in the natural state in the Eastern Cape and the eastern part of the Western Cape, their geographical distributions not overlapping with that of A. africanus (www.plantzafrica.com).
