|F. pyrenaica is a perennial with alternate lance-shaped, glaucous, gray-green leaves. Each stalk bears singular, rarely paired, broadly, bell-shaped, 1 1/2 inches, deep brownish-purple, occasionally yellow flowers, strongly checkered with yellow-green within the tepal. Native to Pyrenees.
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.
