Agapanthus africanus (African lily; syn. Agapanthus umbellatus) is a member of the family Alliaceae and a native of the Cape of Good Hope in South Africa. It is sometimes know as plum plum by native South Africans.
It has a short stem bearing a tuft of long, narrow, arching leaves 10-35 cm long and 1-2 cm broad, and a central flower stalk 25-60 cm tall, ending in an umbel of 20-30 white, or bright blue, funnel-shaped flowers, each flower 2.5-5 cm diameter.
Several cultivars are known, such as 'Albus' (with white flowers), 'Sapphire' (dark blue flowers), 'Aureus' (leaves striped with yellow), and 'Variegatus' (leaves almost entirely white with a few green bands). There are also double-flowered and larger- and smaller-flowered cultivars.
During the summer they require plenty of water and are very effective on the margins of lakes or by running streams, where they thrive. They may be propagated from offsets or by dividing the rootstock in early spring or autumn.
