Bluestem yucca

Yucca gigantea is usually less than 6 m (20 ft) in height. It may have a thick, single trunk or be multitrunked resulting from a thickened, inflated, trunk-like lower base similar to an elephant's foot. The exceptionally narrow leaves fan out in clumps. They are strap-like, spineless and up to 1.2 m (4 ft) in length. White flowers are produced in the summer. Mature plants produce erect spikes of pendent flowers up to 1 m (3.3 ft) in length. Flowers are followed by brown, fleshy fruits which are oval and up to 2.5 cm (1 in) long.
