Plants & Availability
Blue yucca, a trunk-forming species, grows to 12 feet tall, with minimal branching near the top. Its distinctive, powder blue leaves are fairly rigid, with yellow margins. These blue leaves are about 3 feet long by 1 inch wide, and have a sharp spine at the tip. In the late spring the blue foliage is complemented by a showy 5 to 6 foot stalk of white flowers. For best growth, provide supplemental water in the summer, and plant in well-drained soils. Blue yucca can be planted in full sun or very light filtered shade.
