Care Instructions

Light: Morning sun with afternoon shade is best in Phoenix; tolerates full sun when acclimated, but avoid intense reflected heat.

Water: Low water once established; water deeply, then let soil dry completely. In Phoenix, occasional summer irrigation improves appearance; reduce watering sharply in winter.

Soil: Very well-drained, sandy or gravelly soil; use a cactus mix in containers and avoid water-retentive planting pockets.

Mature size: Individual rosettes reach about 1–2 feet tall and 2–3 feet wide; offsetting clumps can spread wider.

Bloom: Blooms once after many years, usually in late spring or summer. The flowering rosette dies afterward, but offsets can continue growing.

Evergreen / deciduous: Evergreen.

Growth rate: Slow.
