Description
Rebutia canigueralii, also known as Sulcorebutia canigueralii or Weingartia canigueralii, is a slow-growing cactus that forms a dense clump of many small stems covered with clusters of spines. The stems vary in color from green, grey-green, to dark purple. They grow up to 1.6 inches (4 cm) tall and up to 2 inches (5 cm) in diameter, freely producing offsets that develop roots while still attached to the mother plant. Spines are whitish, grayish, straw-colored, or brown, with a darker base or almost black. Each areole bears 11 to 14 bristly, white, recurved radial spines. Central spines are usually absent.
The flowers are orange-red, lilac, or dark magenta, often bi-colored with yellow or white throats, and usually appear from the basal part of the stems in late spring and remain open for three or four days. They are up to 2 inches (5 cm) long and nearly equal in diameter.
Hardiness
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
If you can grow cacti and succulents successfully, you can likely grow the popular Rebutias 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. Instead of propagating your offsets, let the plant form a large cluster for the best viewing. When it blooms, this will make a stunning display. Lastly, fertilize during the growing season for the best results.
Repot as needed, preferably during the warm season. To repot your Rebutia, ensure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, removing any rotted or dead roots. Treat any cuts with a fungicide. Place the plant in its new pot and backfill it with potting soil, spreading the roots out as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot.
