Yucca filamentosa is a species of flowering plant in the family Asparagaceae native to the southeastern United States as far west as Louisiana, and along the East Coast from central Florida to southeast Virginia. They have become naturalized north along the East Coast to coastal Rhode Island and into parts of the lower Midwest. They are normally hardy in USDA hardiness zones of 5 to 9. Most commonly found in sandy soils, especially in beach scrub and dunes, but also in fields, barrens, and rocky slopes, though it grows well also in silt or clay soils. Its common names include Adam's needle, common yucca, Spanish bayonet, bear-grass, needle-palm, silk-grass, and spoon-leaf yucca. The species is also reportedly naturalized in France, Italy and Turkey.
