Agapanthus is the only genus in the subfamily Agapanthoideae of the flowering plant family Amaryllidaceae. The family is in the monocot order Asparagales. The name is derived from scientific Greek: αγάπη (agape – “love”), άνθος (anthos – “flower”). Some species of Agapanthus are commonly known as lily of the Nile (or African lily in the UK), although they are not lilies and all of the species are native to Southern Africa (South Africa, Lesotho, Swaziland, Mozambique) though some have become naturalized in scattered places around the world (Australia, Great Britain, Mexico, Ethiopia, Jamaica, etc.). They are cultivated throughout warm areas of the world. They can especially be spotted throughout Northern California. Agapanthus is a genus of herbaceous perennials that mostly bloom in summer. The leaves are basal, curved, and linear, growing up to 60 cm (24 in) long. They are rather leathery and arranged in two opposite rows. The plant has a mostly underground stem called a rhizome (like a ginger ‘root’) that is used as a storage organ. The roots, which grow out of the rhizome, are white, thick and fleshy. They have funnel-shaped or tubular flowers, in hues of blue to purple, shading to white. Credit: Wikipedia.
