Description
Rebutia rauschii f. violacidermis is a small cactus that forms clumps of many violet-green to bright mauve stems with characteristic very short black spines. The stems are up to 1.6 inches (4 cm) tall, up to 2 inches (5 cm) in diameter, and covered by flat tubercles. In older plants, the tubercles are arranged in up to 16 spiral lines merging in the apex. Areoles are long, narrow, with short white felt. Spines are completely flattened against the tubercles. Flowers are deep magenta, funnel-shaped, up to 2 inches (5 cm) long, and about the same diameter.

Hardiness

How to Grow and Care
If you can grow cacti and succulents successfully, you can likely grow the popular Rebutia without too much trouble. Their water and light requirements are fairly typical for many cacti species, including a cooling period in the winter to promote better blooming. Watering should be done carefully, allowing the plant to almost dry out between waterings. The cactus mustn't be exposed to prolonged dampness and sitting water. Never let your cactus sit in a dish of water. For the best viewing, instead of propagating your offsets, let the plant for a large cluster. When it blooms, this will make a stunning display. Lastly, make sure to fertilizer during the growing season for the best results.
Repot as needed, preferably during the warm season. To repot a cactus, make sure the soil is dry before repotting, then gently remove the pot.
