Sulcorebutia rauschii 'Purple' (syn. canigueralii)
Sulcorebutia rauschii 'Purple' is a cultivated colour form of Sulcorebutia rauschii, a species native to the high-altitude regions of Bolivia. This form is characterised by its pronounced purple to violet epidermis, which can intensify under strong light or cooler temperatures. The plant develops small, flattened, spherical stems densely covered in spiralling tubercles, each tipped with short, fine spines. In late spring to summer, it produces relatively large, funnel-shaped flowers, typically magenta to reddish-purple, which contrast with the stem colour.
Care Tips:
- Light: Requires bright light with several hours of direct sun daily to maintain its purple pigmentation.
- Water: Water thoroughly during the active growing season, allowing the soil to dry completely between waterings; keep almost dry in winter.
- Humidity: Prefers low humidity; ensure good air movement.
- Media: Use a very free-draining cactus mix with added mineral grit.
- Temperature: Tolerates a range of temperatures but should be kept above 5°C in winter; can withstand short periods of light frost if dry.
- Fertiliser: Apply a diluted, low-nitrogen fertiliser once a month during the growing season.
- Repotting: Repot every 2–3 years in fresh, well-draining soil to maintain health.
