Overview

Ledebouria spp. is a genus of about 50 bulbous geophytes in the family Asparagaceae, native chiefly to sub-Saharan Africa with a few species in India and Madagascar. Plants grow from small bulbs, often sitting partly above the soil surface, and form spreading clumps as they produce offsets. The leaves are lance-shaped to strap-like, 2-10 in (5-25 cm) long, and many species carry green foliage marked with silver, grey, or dark spots and bands, sometimes with purple undersides. Short racemes of small bell- or star-shaped flowers in green, pink, or purple rise on slender stalks 4-16 in (10-40 cm) tall, mainly in spring and summer. The widely grown L. socialis, silver squill, has silver-mottled leaves with purple backs and forms dense colonies of exposed bulbs. The genus grows in grassland, woodland, and rocky sites that are seasonally dry, and most species tolerate drought by dying back to the bulb. All parts contain bufadienolide compounds that are poisonous if eaten by people or animals. Cold tolerance is limited, with most species suited to USDA zones 9 to 11.

Native Range

Ledebouria spp. is native mainly to sub-Saharan Africa, from South Africa north through tropical Africa, with a few species in India, Sri Lanka, and Madagascar. Plants occur in seasonally dry grassland, open woodland, and rocky ground.

Suggested Uses

Ledebouria spp. species are grown as houseplants, container subjects, and rock-garden bulbs in mild climates, grown for their patterned foliage. The clumps of surface bulbs suit shallow pots and dish gardens. In frost-free areas the genus is used as a drought-tolerant groundcover.

How to Identify

Identify Ledebouria spp. by small bulbs that often sit on the soil surface, producing clumps of lance-shaped leaves frequently patterned with silver or dark spots and bands. Slender racemes carry many small green, pink, or purple bell-shaped flowers with reflexed tips. The exposed patterned bulbs and spotted foliage separate it from most other small bulbs.

Care & Maintenance

Care Guide

Ledebouria spp. species grow in bright, filtered light to part sun in gritty, free-draining soil with a pH near 6.0 to 7.0. They follow a seasonal cycle, growing and flowering in the warm months and resting as the soil dries. Watering is reduced or stopped during the dormant period to prevent bulb rot. Most species are frost-sensitive and grow outdoors in USDA zones 9 to 11; in colder regions they are grown as houseplants or in containers moved under cover. The clumps of offset bulbs can be divided when crowded. All parts are poisonous if eaten.

Pruning

Faded flower stalks and dried leaves are removed as the plant enters dormancy. No structural pruning is needed for these bulbous plants. Offsets can be separated during repotting to control clump size.
