How to care for Moonstones

Pachyphytum oviferum · Crassulaceae

succulentmoderate to growtoxicity unknown

Plump, egg-shaped leaves in pastel blue, lilac, and pink cluster like a handful of sugared almonds — few succulents look this ornamental. A Mexican cliff-dweller, it wears a delicate powdery bloom that marks permanently at a touch. It asks for little beyond strong light, gritty soil, and disciplined watering. Water roughly every 16 days while it's growing (about every 35 in winter), give it direct sun, kept above 45°F (7°C) — dry air is fine for it.

Care at a glance

Water: every ~16d growing · ~35d dormant
Light: Direct sun
Humidity: dry air is fine — no extra humidity needed
Keep above: 45°F (7°C)
Feed: every ~60d in season
Repot: every ~3 years

Water deeply only when the soil has been dry for days and the lowest leaves lose a little firmness.

Several hours of direct sun keep the leaves fat and pink-toned; it will stretch surprisingly fast in mere bright shade.

Quarter-strength cactus fertilizer once or twice in the growing season is ample.

Mistakes that kill this plant

  • Frequent shallow watering that keeps the surface damp.
  • Growing it a meter or more from the window until it collapses into a stretched vine.
  • Water droplets sitting among the leaves in cool weather, inviting rot.

Seasonal tips

  • Cool, bright, dry winters bring out the strongest lilac-pink coloring.
  • Propagate spare leaves in spring — they root as easily as echeveria leaves.
  • Handle only by the stem or rootball to preserve the powdery coating.
