|F. crassifolia is a variable perennial with alternate lance-shaped, gray-green leaves. The flowers are borne on stalks. Each stalk bears 1 to 3, broadly, bell-shaped, pendant pale green flowers, usually with faint brown checkering. They are up to 1 inch long. Native to Turkey, Lebanon and Iran.
The large, skunky-smelling bulb is rodent-repellent, and is very succeptible to bulb rot if improperly stored. For best results, plant bulb on its side, at a depth 4 times the diameter of the bulb. Water moderately while in growth, but reduce to almost dry when bulb is dormant. For container plants, repot yearly in fresh soil.
Second year and older plants should be fertilized monthly with half strength fertilizer.
