Agapanthus is a genus of herbaceous perennials that mostly bloom in summer. Agapanthus is commonly known as "Lily of the Nile", but it is not a lily and all of the species are native to South Africa from the Cape to the Limpopo River. Species boundaries are not clear in the genus, and in spite of having been intensively studied, the number of species recognized by different authorities varies from 6 to 10. The type species for the genus is Agapanthus africanus. A great many hybrids and cultivars have been produced and they are cultivated throughout warm areas of the world.
Agapanthus can be grown within plant hardiness zones 9 to 11. In lower-numbered zones, the bulbs should be placed deeper in the soil and mulched well in the fall. Agapanthus can be propagated by dividing the bulbs or by seeds. The seeds of most varieties are fertile. Species in this genus include Agapanthus africanus, Agapanthus campanulatus, Agapanthus caulescens, Agapanthus coddii, Agapanthus comptonii, Agapanthus dyeri, Agapanthus inapertus, Agapanthus nutans, Agapanthus orientalis, Agapanthus praecox and Agapanthus walshii.
