A africanus subspecies africanus is not suitable as a garden plant except in rockeries. They are best grown in containers in a well drained, slightly acid sandy mix and appear happiest if pot bound. They seem to grow best in shallow containers and will flower regularly if fed with a slow release fertiliser.1
These estimates for how long Cape Agapanthus takes to sprout, grow and harvest are from real observations from real gardeners, right around the world.
