Description

Rebutia heliosa is a small, slow-growing cactus with spherical to shortly cylindrical stems. This species is covered in a net of small densely brown areoles with short silvery-white intersecting spines. 

The stems are up to 1.2 inches in diameter and rarely grow taller than 1.4 inches . Flowers are diurnal, long-lasting (about ten days), orange to orange-red, funnel-shaped, up to 2 inches long, up to 1.6 inches in diameter. Fruits are small, globose, and purple.

Environment

Rebutias thrive in bright light and a range of conditions. Many species can be grown in partial shade to full sun. However, as these are mountain species, they do not appreciate high temperatures, which should be avoided. 

It requires rich, fast draining porous cactus soil. Repotting may be done every 2-3 years. Ideally use 50% Potting Soil + 15% cocopeat + 25% Organic manure / Vermicompost + 5% charcoal chips + 5% perlite.

Water the soil abundantly when it is dry to the touch. Allow soil to drain thoroughly before watering again. Allow the soil mix to become nearly dry between waterings, but then water thoroughly. Suspend watering in the winter, but mist occasionally.

During the growing season, fertilize with a cacti fertilizer mix.
