Cereus Peruvianus Monstrose 'Petra'

Common Names: Petra Monstrose Cereus, Ming Thing Cactus, Curly Cereus

Appearance

A rare and highly sculptural cactus with contorted, twisted, and irregular stems caused by a natural monstrose mutation.
Thick blue-green stems grow in unpredictable, coral-like formations with short, scattered spines.
Slow-growing and unique, each plant develops its own surreal, one-of-a-kind shape.

Care & Growing Conditions

Light: Prefers bright sunlight to full sun; strong light maintains healthy growth and compact form.
Soil: Well-draining cactus or sandy soil mix.
Watering: Drought-tolerant; allow soil to dry completely between waterings. Reduce watering in winter.
Temperature: Thrives in USDA zones 9–11; protect from temperatures below 30°F (-1°C).
Humidity: Prefers low humidity and dry conditions.

Flower

Produces large, fragrant white flowers at night on mature plants.
Blooming is rare in container-grown monstrose varieties but spectacular when it occurs.

Toxicity

Non-toxic to humans and pets. Spines are mild but can irritate skin if handled carelessly.
