Yucca filimentosa / Yucca Root
Yucca filamentosa (Yucca Root) is a species of flowering plant in the family Asparagaceae. Native to the south-eastern United States, from south-east Virginia to Florida, and as far west as south Texas. The species is also reportedly naturalised in France, Italy and Turkey.
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.
Usually trunkless, it is a multisuckering evergreen shrub with heads of 75 cm (30 in) long. It is fully hardy, though in cultivation it benefits from a sheltered position away from winter winds. Y. filamentosa is widely cultivated in mild temperate and subtropical climates as a broadleaved evergreen plant. It needs full sun and a well-drained soil.
