distribution_en:
description_en: Genus of 2 species of single-stemmed palms from rocky, arid areas in S.W. USA and N. Mexico. Deeply lobed, fan-shaped leaves are borne in terminal heads that form a dense, shaggy thatch on the trunk as they die back. Because of the fire risk, this dead material is often removed in cultivation. Tubular, creamy white or creamy pink flowers, each with 3 petal lobes, are borne in slender, arching panicles between the leaves. In frost-prone climates, grow young plants as houseplants or in a temperate or warm greenhouse. In warmer areas, use as lawn specimens or as avenue trees.
hardiness_en: Frost tender.
cultivation_en:
propagation_en: Sow seed at 24°C (75°F) in spring.
