Aylostera heliosa subsp. cajasensis (Donald) Mosti & Papini
Rebutia heliosa subsp. cajasensis, Rebutia heliosa var. cajasensis
Aylostera heliosa subsp. cajasensis, formerly known as Rebutia heliosa var. cajasensis, is a small cactus with grey-green covered in glassy, silvery, pectinate spination from coppery-colored areoles. This cactus is usually solitary in nature, but in cultivation, it offsets rapidly to form a dense clump with age.
The flowers are funnel-shaped, orange-red to red, up to 2 inches (5 cm) long and 1.6 inches (4 cm) in diameter, emerge from low down on the stems, and appear in such profusion in spring.
Aylostera heliosa subsp. cajasensis was discovered in the Cajas Pass northwest of Tarija in Bolivia, at an elevation of about 8,200 feet (2,500 m). It is not recognized as a separate subspecies and is treated as a synonym of Aylostera heliosa or by some authors of Aylostera deminuta.
The subspecific epithet "cajasensis (kah-yah-SEN-sis) means "Of or from Cajas" and refers to the location where this plant was discovered.
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 pretty 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, ensure fertilizer during the growing season for the best results.
Repot as needed, preferably during the warm season. To repot a cactus, ensure the soil is dry before repotting, then gently remove the pot.
