Description
Rebutia heliosa subsp. cajasensis is a small cactus with grey-green stems and fine silvery spider-like spines that almost completely cover the small stems in a spiral pattern. It is usually solitary in nature, but it offsets rapidly to form a clump with many heads in cultivation. The areoles are small, elongated, and with a brown felt. Flowers are funnel-shaped, orange-red or red, up to 2 inches (5 cm) long and 1.6 inches (4 cm) in diameter.

Hardiness
USDA hardiness zone 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 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 truly beautiful 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.
