Lily of the Nile Agapanthus

This is a genus of 6 plants in the amaryllis family (Amaryllidaceae) native to southern Africa and grows in upright clumps from fleshy rhizomes that produce short, tuberous roots. There are both evergreen and deciduous species. The Genus name is derived from Ancient Greek ἀγάπη (agápē) 'love' and ἄνθος (ánthos) 'flower'.

Plant in full sun to partial shade in sandy-loam well-drained soils. The rhizomes should be planted 1 inch deep and 8 inches apart. If growing in a pot allow the plant to become rootbound as it will bloom best under those conditions. Propagation from seed can take up to 5 years before blooming occurs so division is best. Divided plants may not bloom in the first year. This plant is seldom damaged by deer. Cultivars are available.

Tufts of strap-like arching leaves are produced on short stems and are 12-24 inches long and 1-2 inches wide. Flowers are produced in clusters held above the foliage and are tubular or bell-shaped in shades of blue, purple or white with a darker stripe down the center of each petal. Bloom time is summer and in frost-free areas will bloom into fall.

Evergreen types should be grown year-round, treating them as houseplants during the winter in areas that receive frost. The deciduous ones can be stored in a cool, dark place in above-freezing temperatures in areas north of zone 7.  If leaving the deciduous types in the ground provide mulch for protection and do not plant in an area that stays wet.

Use in the border, mass planted or in a container. Use in a cutting or cottage garden.

Insects, Diseases, and Other Plant Problems:  No significant problems. Root rot can occur in too wet soils. Some species are listed as invasive in some countries.
