Myrtillocalycium cv. 'Polyp'

• Unusual Appearance: It's a colorful red and green columnar cactus with a unique and somewhat unstable growth pattern.
• Graft Chimera: It's a combination of two different species, which makes it somewhat unstable and prone to reverting to the original red Gymnocalycium shoots.
• Unstable Nature: The red parts, lacking chlorophyll, need the green Myrtillocactus base to survive.
• Sterile: Being a genetic mutation, it's sterile and can only be propagated asexually (through cuttings or grafting).

• Light: Start in light shade when young and transition to a brighter spot as it matures.
• Soil: Use a well-draining soil mix with gravel added for drainage. It prefers a slightly richer organic content than other cacti.
• Watering: Water regularly in summer, but allow the soil to dry out completely between waterings. Reduce watering in autumn and stop completely in winter.
• Fertilizer: Fertilize sparingly, about once a year during the growing season (April-September) with a well-balanced cactus fertilizer.
• Repotting: Repot every year or two, or when the plant outgrows its pot.

Important Note: The red areas of the "Polyp" lack chlorophyll and rely on the green rootstock for survival. This makes it crucial to provide proper care to ensure the entire plant thrives.
