- Description
-
Sword lily is a genus of flowering bulbs in the Iridaceae (iris) family. The plant is distinguished by long, sword-shaped green leaves in upright fans and funnel-shaped flowers on slender stalks that open one at a time from bottom to top. The genus, which hails from Africa, Madagascar, and Eurasia, includes over 300 species in a range of flower colors.
Sword lilies prefer full to afternoon sun, protection from strong winds, and rich, well-drained soil; however, they will adapt to most soils except heavy clay. They thrive in damp borders so do not allow soils to dry out.
The bulbs are tender so delay planting until after the last frost and the soil has had time to warm. The bulbs are hardy in zones 7 to 10. In cooler environments, sword lilies are best treated as annuals. The bulbs can be dug up in the fall and replanted year after year.
The flowers are fragrant and are excellent cut flowers. Make consecutive plantings to extend the flowering season. Sword lilies also grow well in containers and in garden borders.
Diseases, Insects, and Other Plant Problems: Susceptible to Botrytis, crown rot, rust, wilt, and mosaic virus. Watch for aphids, mealy bugs, spider mites, and thrips. If thrips or fungus were a problem during the growing season, consider treating corms with an insecticide or fungicide prior to storage.
