Description
Asphodelus fistulosus is an annual or short-lived perennial herb with a hollow stem that grows up to 28 inches (70 cm) tall. The root system has a series of tuber-like parts at the base of the stem. The plant forms a large tuft of rounded, hollow, onion-like, up to 12 inches (30 cm) long leaves. The inflorescence is a panicle with widely spaced flowers. Each flower is up to 0.5 inches (1.2 cm) wide with six tepals, generally white or pale pink, with a neat central longitudinal stripe of brown to reddish-purple. Flowers are diurnal, closing at night in overcast or low-light weather conditions. Fruits are rounded capsules containing six seeds.
How to Grow and Care
Grow Asphodels in moderately fertile, well-drained soil in full sun. It does not tolerate heavy, poorly-drained soil. Irrigate occasionally to very little in coastal gardens. They are considered hardy to USDA zone 6. It tolerates temperatures down to 14ºF (-10ºC). Great as a border or accent plant.
Propagate Asphodels by seed, sown in pots in a cold frame in spring, or propagate by division after flowering. Although you can cut back flower stems after flowering, the seed heads are attractive, so they can be left.
