Beaked Yucca (Yucca rostrata): Blue Globe Trunked Beauty

Overview

Beaked Yucca (Yucca rostrata) is one of the most ornamental trunk-forming yuccas. A dense, symmetrical globe of narrow, pale blue-green leaves with yellow margins and a sharp terminal spine crowns a stout, fibrous trunk. The leaves are flexible and shimmer in the wind. In spring, a tall spike bears large, white, bell-shaped flowers. Extremely cold hardy (zone 5) and drought-tolerant. Native to West Texas and northern Mexico. A stunning architectural specimen for xeric gardens, providing year-round blue color and form.
