General Description

The hybrid cross between Crinum bulbispermum and C. moorei yields Powell's crinum lily, which blooms in shades of white to soft pink. A bulbous perennial, it tends to be among the most resilient of all crinums for gardens. This crinum lily is notable for its large six-petal, trumpet- to bell-shaped flowers that bloom during the warm months. The leaves are strap-shaped and glossy, evergreen in mildest climates. They emerge from the bulb in a tight bundle and form an arching fountain as they extend. The leafless flower stems are topped by a cluster of outward-facing or slightly drooping flowers.

Powell's crinum lily grows and flowers best in nearly full sun to partial shade in fertile well-drained soil. Amend both sandy and clay soils with organic matter prior to planting. It needs constant moisture during growth but when it is dormant over the winter it endures best and is hardier if the soil is dry. In colder winter areas, layer mulch over the bulb for added protection to improve survival over winter. Use any crinum lily as a specimen or a summer accent in mixed beds and borders. The smaller mature size and durability of this crinum makes it among the best for houseplant culture. Cut off the old flower stalks to improve the look of the plant and to coax repeat flowering later.
