Blue Yucca – Towering Powder Blue Trunk-Forming Yucca

Blue Yucca

A trunk-forming yucca, Blue Yucca (Yucca rigida) grows to 12 feet tall with minimal branching near the top. Its distinctive powder-blue leaves have a pronounced spine at the tip—avoid planting near traffic. In summer, a showy 5- to 6-foot stalk of white flowers emerges. For best growth, provide supplemental water in summer and plant in well-drained soils.
