|'Adiyaman' is a robust perennial with sturdy, upright stems bearing alternate, lance-shaped leaves, with a glaucous, gray-green color. This cultivar is taller, up to 5 inches in height, and more free flowering than the species. The flowers are borne along stalks. Each may have up to 30, conical, narrow, bell-shaped, pendant, brown-purple flowers, up to 3/4 inches long. 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.
