Yucca baccata
Light: Full sun to light shade; afternoon shade is helpful in Phoenix. Avoid intense reflected heat from west-facing walls.
Water: Low water once established. Water deeply but infrequently, allowing soil to dry thoroughly between waterings. Provide occasional supplemental water during prolonged Phoenix summer drought.
Soil: Very well-drained sandy, gravelly, or rocky soil; tolerates alkaline conditions. Avoid waterlogged soil and poorly drained clay.
Mature size: Typically 3–5 feet tall and 4–6 feet wide; spreading colonies can become wider. Flower stalks may reach 6 feet.
Bloom: Creamy white flowers in spring, usually March–May. Mature plants may bloom irregularly; flowering does not kill the rosette.
Evergreen / deciduous: Evergreen.
Growth rate: Slow.
