- Growing Difficulty
- Intermediate
- Lifespan
- Perennial (decades)
- Size
- 6-10cm wide, up to 30cm tall
- Watering
- Minimal
- Lighting
- Full sun; light is needed for good spine color
- Watering
- It dislikes wet conditions, so water sparingly even in the spring-to-autumn growing season. Water only after the soil has dried completely and never leave the pot wet.
- Dormancy Care
- In winter withhold water to let it go dormant and keep it dry. Resume watering gradually once it warms up in spring.
- Cold
- Fairly cold-tolerant if kept dry
- Soil & Repotting
- Use a very fast-draining mix so water never sits in the pot. Growth is slow, so repotting once the roots fill the pot is enough.
