SCIENTIFIC NAME: Yucca rostrata 'Sapphire Skies'

COMMON NAME: Sapphire Skies Beaked Blue Yucca

GARDEN SIZE: 8-10 ft. tall and 3-4 ft. wide in 10 years; 12-15 ft. tall with age in ideal conditions

GROWTH RATE: Moderate

USDA ZONE: 5 to 11

EXPOSURE: Full Sun

WATER & SOIL: These desert-adapted species require gritty, sandy, or rocky soils with excellent drainage. They prefer dry conditions and minimal watering once established, as excess moisture—especially in winter—can lead to rot.

HABIT (FORM): Upright, single trunk with dense, symmetrical crown

FOLIAGE: Evergreen, narrow, stiff baby blue leaves shorter than typical species

FLOWERS: Showy white spike blooms at full maturity, in summer

PLANT ORIGIN: Found in Texas and northern Mexico

WILDLIFE SUPPORT: May provide some nesting sites and shelter for birds and small mammals, but does not serve as much of a host for local insects and wildlife. May provide food for insects in the spring.

FERTILIZING: These species thrive in lean soils and rarely need supplemental fertilizer. If desired, use a light application of cactus or succulent fertilizer in spring to encourage healthy growth.

PRUNING: Very low-maintenance. Remove spent flower stalks and any dead or damaged leaves as needed, typically in late winter or early spring. Trunk-forming species may have dead leaves trimmed for a cleaner appearance.

TOXICITY: Generally considered mildy to moderately toxic to humans and pets.

USES: Excellent as architectural accents, borders, or container specimens. Ideal for xeriscaping, rock gardens, and pollinator-friendly landscapes, with striking blooms and bold evergreen foliage that provide year-round interest.
