Rebutia fiebrigii is a compact, cold-hardy cactus species native to the mountainous regions of Bolivia, where it thrives in rocky, well-drained soils at elevations between 8,000 and 13,000 feet. Belonging to the Rebutia genus—famous for its small stature and show-stopping blooms—this species is a favorite among collectors, rock garden enthusiasts, and windowsill growers alike.

The plant forms small, globular or slightly cylindrical stems, typically growing no more than a few inches tall and wide. These rounded green stems are densely covered with fine white spines that radiate outward in a symmetrical star pattern. The body of the cactus remains relatively low to the ground, often forming clumps over time as it offsets freely, creating attractive clusters that become more striking as they mature.

Despite its modest size, Rebutia fiebrigii puts on a truly spectacular floral display. In spring and early summer, the plant bursts into bloom with brilliant orange, fiery red, or sometimes yellow flowers that often appear in such abundance they completely obscure the cactus beneath. The funnel-shaped flowers emerge from the sides of the stem rather than the top, giving the plant a crown-like appearance—hence one of its common names, “Orange Crown Cactus.”

These stunning blooms make Rebutia fiebrigii a standout feature in any cactus collection. Even a single plant can produce dozens of flowers in one season under the right conditions. The vibrant contrast between the delicate, spiny green stem and the vivid flower colors makes it a showpiece whether grown indoors or out.

One of the most appealing characteristics of Rebutia fiebrigii is its adaptability. Unlike many cacti, it can tolerate cooler temperatures and even brief periods of frost, provided the soil remains dry. This resilience makes it well suited for outdoor cultivation in warmer parts of USDA zones 9–11 and for container culture elsewhere. During winter dormancy, it should be kept cool and nearly dry to encourage flowering in the following season.

Growing Requirements

Light: Prefers bright indirect sunlight or morning sun with some afternoon shade, especially in hot climates. Can tolerate more direct sun if acclimated gradually.
Soil: Requires well-draining cactus mix; sandy or gritty soil is ideal.
Water: Water thoroughly during the growing season (spring and summer), allowing the soil to dry completely between waterings. Reduce or stop watering in winter.
Temperature: Ideal temperatures range from 50°F to 85°F. Can tolerate light frost but should be protected from prolonged freezing.
Fertilizer: Use a diluted cactus fertilizer during active growth once a month. Avoid fertilizing in the dormant season.
Repotting: Repot every 2–3 years or when the cluster outgrows its pot. Allow roots to dry before repotting to prevent rot.
