Namibian Grape (Cyphostemma juttae)

Cyphostemma juttae

Namibian Grape (Cyphostemma juttae)

Endemic to arid Namibia, this remarkable pachycaul succulent develops a massive, bottle-shaped water-storing caudex covered in attractive, peeling papery bark. In the warm season, it produces large, succulent, wax-coated serrated leaves accompanied by striking clusters of grape-like red berries that are toxic if ingested. Deciduous in winter, it stands as an architectural, highly prized specimen among succulent collectors.

📋 Core Botanical Care Parameters

☀️ Light Requirements

Full sun to intense bright light; requires at least 6-8 hours of direct sunlight daily to promote a robust, swollen caudex.

💧 Watering Frequency

🏺 Soil Mix

70% coarse mineral aggregate (pumice, volcanic lava grit, coarse perlite) + 30% organic cactus peat mix.

❄️ Cold Tolerance

-2°C (USDA Zone 9b)

🌱 Propagation Method

Seed sowing in spring following warm-water soaking (most reliable) or rooted dormant stem cuttings.

⚠️ Toxicity Warning
