Yucca aloifoliaLinnaeus, Species Plantarum 1: 319. 1753. is the type species for the genus Yucca. Common names include aloe yucca, dagger plant, and Spanish bayonet. It grows in sandy soils, especially on sand dunes along the coast.
Range Yucca aloifolia is native to the Atlantic and Gulf Coasts of the United States from southern Virginia south to Florida and west to the Texas Gulf Coast, to Mexico along the Yucatán coast, and to Bermuda, and parts of the Caribbean. Normally, Yucca aloifolia is grown in USDA zones 8 through 11. It is a popular landscape plant in beach areas along the lower East Coast from Virginia to Florida.
Yucca aloifolia has become naturalized in Bahamas, Argentina, Uruguay, Italy, Pakistan, South Africa, Queensland, New South Wales, and Mauritania. It is common in gardens and parks of the Iberian Peninsula.
Description Yucca aloifolia has an erect trunk, in diameter, reaching up to tall before it becomes top heavy and topples over. When this occurs, the tip turns upward and keeps on growing. The trunk is armed with sharp pointed straplike leaves with fine-toothed edges, each about long. The young leaves near the growing tip stand erect; older ones are reflexed downward, and the oldest wither and turn brown, hanging around the lower trunk like a Hawaiian skirt. Eventually the tip of the trunk develops a long spike of white, purplish-tinged flowers, each blossom about 4 in (12.7 cm) across. After flowering, the trunk stops growing, but one or more lateral buds are soon formed, and the uppermost becomes a new terminal shoot. Yucca aloifolia also produces new buds, or offshoots, near the base of the trunk, forming the typical thicket often observed in dry sandy and scrub beach areas of the southeastern United States.Flora of North America vol. 26, p. 429. 2006.CONABIO. 2009.
