Agave murpheyi
Light: Full sun to light shade; afternoon shade is beneficial in Phoenix locations with intense reflected heat.
Water: Low water once established. Water deeply but infrequently, allowing soil to dry thoroughly between waterings. Occasional summer irrigation improves appearance; reduce watering substantially in winter.
Soil: Very well-drained sandy, gravelly, or rocky soil. Tolerates alkaline soil; use raised planting areas where drainage is poor.
Mature size: Approximately 2–3 feet tall and 3–4 feet wide per rosette; colonies spread wider. Flower stalks can reach 10–15 feet.
Bloom: Blooms once at maturity, often after 10–20 years, depending on growing conditions. The flowering rosette dies afterward, but offsets continue growing.
Evergreen / deciduous: Evergreen.
Growth rate: Slow to moderate; growth improves with occasional warm-season watering.
