Moon Cactus 'Hibotan' (Gymnocalycium mihanovichii 'Hibotan'): The Classic Red Grafted Cactus

Moon Cactus 'Hibotan' is the iconic, bright red (or yellow, orange, pink) mutant seedling that lacks chlorophyll and must be grafted onto a green rootstock (usually Hylocereus) to survive. The colorful, ribbed top forms a flattened sphere up to 2 inches wide. It’s a novelty plant widely sold as a gift, but with proper care, the graft can last for years. The species is native to Paraguay and Argentina.

Care Tips

Bright, indirect light; avoid hot sun on the colored top. Water when the rootstock soil is dry. Keep above 50°F (10°C). The rootstock does the photosynthesis; the scion is a parasite. If the scion produces offsets, they can be regrafted.
