Accepted Scientific Name: Rebutia heliosa v. melanistic
Origin and Habitat:
Rebutia heliosa v. melanistic is native to the mountainous regions of Bolivia, where it thrives on rocky slopes and in well-drained soils at high altitudes. These harsh environments, with intense sunlight and cool temperatures, contribute to the species’ resilience and unique adaptation to arid conditions.
Description:
This small, globular cactus grows to about 1.5-2 inches in height and diameter, often forming clumps over time. It is characterized by its tightly arranged, spiraling tubercles and dark spines, which give it a striking appearance. During the blooming season, it produces bright orange to reddish-orange flowers that beautifully contrast with its dark body.
