Rebutia heliosa subsp. teresae Kníže, Říha & Šeda
Rebutia teresae, Rebutia heliosa var. teresae, Aylostera theresae
Rebutia heliosa subsp. teresae is a long-spined form of Rebutia heliosa. It is a dwarf, low-growing cactus, usually solitary in nature, but in cultivation it offsets rapidly to form a clump with many heads, densely covered in brown areoles with white, pectinate spines, giving it a silvery appearance. The spines are not quite as appressed as in the typical subspecies and the areoles are not as elongated, but the broader bodies are nevertheless covered in glassy, pectinate spination, emerging from brown to coppery-colored areoles. The flowers are more intensely red-orange with a pinkish blush to the outer tepals.
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 almost dry out between waterings. It's imperative that the cactus is not 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 cacti, make sure the soil is dry before repotting, then gently remove the pot… – See more at: How to Grow and Care for Rebutia
