Sulcorebutia rauschii – Rausch's Crown Cactus

Sulcorebutia rauschii (syn. Rebutia canigueralii f. violacidermis), commonly known as Rausch's Crown Cactus, is a compact, clumping gem native to the high-altitude rocky soils of Bolivia's Chuquisaca department (1,800–2,400 m). Its deep blue-green to purple-tinged heads and vibrant magenta flowers make it one of the most visually striking small cacti in any collection.

General Information & Care

• Origin: Bolivia (Chuquisaca), growing in gritty, rocky soil at high elevations.
• Appearance: Small, clumping globose to cylindrical heads with distinctive spiral tubercles and a near-spineless look.
• Growth: Slow-growing but prolific offsetter — forms impressive dense clusters over time.
• Flowers: Bright pink to magenta blooms emerging from the base or apex in late spring to summer.
• Light: Bright, full sun preferred — enhances the plant's vivid coloration.
• Watering: Use fast-draining gritty mix; allow to dry completely between waterings. Keep dry in winter when temps drop below 50°F (10°C).
