Plant Common Name

Asian Crinum Lily, Giant Crinum, Poisonbulb

General Description

The Asian crinum lily is a large, free-blooming, fragrant, bulbous perennial for warm climates or containers. Native to tropical Southeast Asia, it grows and increases vigorously in suitable conditions, and blooms continuously. In marginal regions, frost may kill the leaves but the plant recovers and new leaves grow with the return of mild temperatures. Over time the bulb grows larger and the broad strap-shaped leaves emerge in a trunk-like mass that separates into individual flaring, arching, glossy leaves. The bulb produces daughter bulbs freely and one plant eventually becomes an imposing mass. The thick succulent flower stems are topped by fountain-like clusters of large fragrant flowers with narrow widely-separated pure-white petals that account for one of its common names, spider lily. All parts of the plant are toxic.

Asian crinum lily grows and flowers best in full sun on moist soil that is rich in humus. Soil drainage may vary from average to well drained. Once it is well-established, the plant tolerates periods of dry conditions. It is used as a specimen plant for its size and sculptural shape. Planted near the house, it slightly perfumes the local air. In a container, it needs full sun and regular watering during growth.
