It is native to the deserts of the southwestern United States and northwestern Mexico. It is a perennial herb which produces a slender, unbranching, sometimes twisting stem up to 50 centimeters tall, but generally shorter. There is a basal leaf 10 to 20 centimeters long which is waxy in texture and withers at flowering. The flower cluster bears 1 to 6 erect bell-shaped flowers in a loose cluster. Each flower has three sepals and three petals which are usually spotted at the bases. The petals may be 5 centimeters long and are yellow, orange, or red in color. The fruit is an angled, striped capsule up to 6 centimeters in length. (contributed by Mary Ann Machi)
