|F. delphinensis is a perennial with alternate linear, lance-shaped, glaucous, gray-green leaves. Each stem bears singular, broadly, bell-shaped flowers, 2 inch long, gray-purple, outside and white within, with purple-brown checkering. Native to the French and Italian Alps.
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.
