Gymnocalycium Mihanovichii (Grafted onto Hylocereus)

Common Names: Moon Cactus, Hibotan Cactus, Ruby Ball Cactus

Appearance

A small, brightly colored, globular cactus that lacks chlorophyll, making it appear red, pink, yellow, orange, or even purple.

Typically grafted onto a green Hylocereus cactus base to survive, as it cannot photosynthesize on its own.

Usually grows up to 2 inches (5 cm) in diameter, with the grafted base reaching up to 12 inches (30 cm) tall.

Care & Growing Conditions

Light: Prefers bright, indirect light; too much direct sun can cause sunburn.

Soil: Well-draining, sandy, or cactus mix soil.

Watering: Needs moderate watering; allow the soil to dry out completely between waterings.

Temperature: Thrives in USDA zones 10-11; should be kept above 50°F (10°C) and protected from frost.

Humidity: Prefers dry conditions and does not tolerate excessive moisture.

Flower

Occasionally produces small, pink or white flowers on mature plants, though flowering is rare in grafted specimens.

Toxicity

Non-toxic to humans and pets, making it safe for households.
