Identifying a Red-Topped Cactus – Gymnocalycium Hibotan

Moon Cactus (Grafted)

The photo shows a bright red top on a green base—a Gymnocalycium hibotan (moon cactus), a grafted plant where the colorful top lacks chlorophyll.

Care

• Water only when soil is completely dry.
• Bright indirect light; avoid direct sun.
• Desk lamp is insufficient; place near a west window.
• These grafts are short-lived (often 1–2 years).
