Origin of Name

Rebutia pulvinosa's nomenclature reflects both its botanical characteristics and taxonomy. The genus name "Rebutia" is in honor of Pierre Rebut (1828–1898), a French cactus enthusiast and nurseryman known for his extensive collection and cultivation of cacti. The species name "pulvinosa" is derived from Latin, meaning "cushiony" or "pulvinate," referring to the plant's dense, cushion-like clusters of stems. This naming convention highlights the plant's compact and mounded growth habit, reminiscent of small cushions.

Technical Description of Plant

Rebutia pulvinosa is a small, globular cactus that forms low, dense clumps. It is highly valued for its prolific flowering and ease of care, making it a favorite among cactus enthusiasts. The stems are green, spherical to short cylindrical, and can reach up to 2 inches in height and diameter. They are covered in small, white areoles from which emerge fine, short spines that are relatively soft to the touch. The true charm of Rebutia pulvinosa lies in its flowers; the plant produces bright orange to red flowers in late spring to early summer. These flowers are large in comparison to the body of the cactus, encircling the stem's crown, creating a striking display.

Origin of Plant

Rebutia pulvinosa is native to Bolivia, where it thrives in high-altitude regions. Adapted to rocky substrates and cliff faces, it has developed a compact form to minimize exposure to harsh winds and maximize water retention, typical of plants that inhabit arid, mountainous environments.

Conservation Status

The conservation status of Rebutia pulvinosa specifically has not been widely documented. However, like many cacti native to South America, it could face threats from habitat destruction and illegal collection. Cultivation in controlled environments such as home gardens and botanical collections can help preserve the species and reduce pressure on natural populations.

Care Instructions

Rebutia pulvinosa thrives in bright, indirect light but can tolerate direct morning and late afternoon sun. It prefers a well-draining cactus mix to prevent root rot. Water moderately during the active growing season, allowing the soil to dry completely between waterings, and reduce watering significantly in the winter months. This cactus is relatively cold-tolerant compared to other succulents but should be protected from frost. Fertilize lightly with a cactus-specific fertilizer in the spring to encourage blooming. Being compact, it is well-suited for container gardening, making it a versatile choice for both indoor and outdoor settings.
