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 Greek: ἀγάπη, ἄνθος. Some species of Agapanthus are commonly known as lily of the Nile, or African lily in the UK.
Agapanthus are known for their large, blue drumstick-headed flowers in summer. These South African perennial plants are equally suitable for borders and large containers. Agapanthus look great when planted with drifts of ornamental grasses, sun-loving rudbeckias and goldenrod (Solidago). Most agapanthus are hardy and their leaves die down in winter. Evergreen forms are more tender and usually need the shelter of a greenhouse from early winter to spring.
