|F. thunbergii is a perennial with alternate, opposite, or whorled, linear, glossy, mid-green leaves. The flowers are borne on loose racemes of 2 to 6 widely bell-shaped or cup-shaped, nodding, in a creamy white color with faint checkering or veined green. They are up to 1 1/2 inches long. Native to C. China.
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.
