Description
Rebutia heliosa subsp. teresae, also known as Rebutia teresae, is a long-spined form of Rebutia heliosa. It is a dwarf cactus, solitary at first, then offsetting profusely to form a clump of many stems densely covered in brown areoles with white pectinate spines, giving them a silvery appearance. The spines are not as appressed, and the areoles are not as elongated as in the typical subspecies.
The flowers are intensely red-orange with a pinkish blush to the outer tepals.
Hardiness
USDA hardiness zone 9a to 11b: from 20 °F (−6.7 °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 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.
