Eriosyce Gymnocalycium mihanovichii ‘Black’ is a unique and visually striking cultivar within the Gymnocalycium mihanovichii species, often admired for its deep, almost black appearance. Native to South America, specifically Argentina and Paraguay, this cactus stands out due to its dramatic coloration and minimalistic aesthetic.
The body is globular to slightly flattened, with smooth ribs that run vertically around the plant. The coloration can range from dark green to blackish-purple, depending on light conditions and growing environment. Small, pale spines adorn the areoles, contrasting subtly against the dark body.
This species is capable of producing small, funnel-shaped flowers that typically come in shades of pale pink to white. These blooms often appear during the growing season, adding an elegant charm to its otherwise dark and mysterious appearance.
How to Care
- Light: Thrives in bright, indirect light. Avoid prolonged exposure to direct sunlight, which can cause scorching.
- Watering: Allow the soil to dry out completely between waterings. Reduce watering significantly during winter.
- Soil: Prefers a well-draining cactus or succulent mix with added grit or sand for better aeration.
- Temperature: Maintain temperatures between 15°C and 30°C (59°F to 86°F). Protect from frost.
- Fertilizer: Feed once a month during the growing season with a low-nitrogen cactus fertilizer.
- Repotting: Repot every 2-3 years to refresh the soil and accommodate growth. Handle gently to avoid damaging the delicate roots.
- Propagation: Propagate through offsets or grafting. The dark variety may require grafting for long-term health and coloration.
