The Striking Purple Cactus - Sulcorebutia rauschii 'Purple'

Sulcorebutia rauschii 'Purple' is a small, visually arresting cactus with a deep purple to violet hue, originating from Bolivia. This unique cultivar is known for its spiralling tubercles and contrasting greenish areoles, often forming dense clusters over time. It produces vivid magenta flowers in spring, adding to its ornamental appeal.

Distinctive Features

• Rich Purple Colouration: Its deep purple hue is intensified under bright sunlight, making it a stunning addition to any cactus collection.
• Spiralled Tubercles: Unlike many cacti, it has tubercles arranged in an elegant spiral pattern, enhancing its texture.
• Cluster-Forming Growth: Over time, it produces multiple offsets, creating a striking mound of compact, spherical stems.

Care Tips

• Light: Prefers full sun to partial shade; strong light enhances its purple pigmentation.
• Water: Water sparingly, allowing the soil to dry completely between waterings.
• Humidity: Thrives in dry conditions and does not tolerate excessive moisture.
• Media: Well-draining cactus mix with added perlite or grit is essential.
• Temperature: Prefers warm conditions (18–30°C); can tolerate short periods near freezing if kept dry.
• Fertiliser: Use a diluted cactus fertiliser during the growing season (spring to summer).
• Repotting: Infrequent repotting is needed; repot only when the cluster outgrows its pot.

Additional Notes

• This cactus enters dormancy in winter; reduce watering significantly during this period.
• It is non-toxic to pets, making it a safe choice for households with animals.
• Best grown in containers due to its compact size and slow growth rate.

With its striking purple hue and manageable care needs, Sulcorebutia rauschii 'Purple' is a must-have for cactus enthusiasts. Given the right conditions, it will reward growers with its unique form and vibrant flowers.
