Yucca aloifolia
Light: Full sun to partial shade; afternoon shade helps prevent leaf scorch in Phoenix, especially near heat-reflecting walls.
Water: Low water once established. Water deeply, then let soil dry thoroughly; provide occasional supplemental irrigation during prolonged summer heat. Reduce watering in winter.
Soil: Very well-drained sandy or gravelly soil; tolerates alkaline conditions. Avoid poorly drained clay and persistently wet planting sites.
Mature size: Usually 10–15 feet tall and 3–5 feet wide per crown; branching, suckering clumps can spread 6–10 feet or more.
Bloom: Typically blooms in spring or summer once mature; established plants can flower again in subsequent years.
Evergreen / deciduous: Evergreen.
Growth rate: Slow to moderate, depending on irrigation and growing conditions.
