Description

This is a genus of 6 plants native to southern Africa and grows in upright clumps from fleshy rhizomes that produce short, tuberous roots. Tufts of strap-like arching leaves are produced on short stems and are 12-24 inches long and 1-2 inches wide. Most are evergreen and stay attractive even when not in bloom although there are deciduous types. Flowers are produced in clusters held above the foliage and are tubular or bell-shaped in shades of blues, 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.

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. Use in the border or on the patio in a container.

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 with mulch for protection and do not plant in an area that stays wet.

This plant can be propagated by seed or dividing the rhizomes. Starting 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.
