Weingartia trolli rosa (Syn. Rebutia neocumingii ssp. trolii)

Origin of NameThe name "Weingartia" honors Wilhelm Weingart, a German cactus enthusiast and collector active in the early 20th century. The species was originally named to honor Walter Troll, a notable German botanist recognized for his extensive work in plant morphology and systematics. The name "trolli" reflects this dedication, linking the cactus species to Troll's legacy in the field of botany.

Origin of Plant

Weingartia trolli rosa is native to the Bolivian Andes, specifically flourishing in regions where the elevation ranges from 2,000 to 3,000 meters. The plant is adapted to the rocky, arid environments typical of these high-altitude areas, where it has evolved to make efficient use of limited water resources and abundant sunlight.

Description

Weingartia trolli rosa is a small, globular cactus with a charming appearance that is beloved by collectors. Its spherical body is covered in spiny areoles, with spines that range in color from pale yellow to brownish hues. The cactus is notable for its eye-catching pink to rose / orange-colored flowers, which bloom amidst its spine-covered surface. The flowers, typically appearing in spring or summer, provide a lovely display that attracts cactus enthusiasts and pollinators alike.

Conservation Status

While specific conservation data for Weingartia trolli rosa may not be well-documented, habitat loss and environmental changes pose potential risks. Conservation efforts focus on habitat protection and ex-situ cultivation to preserve this species. Cultivation outside of its natural habitat helps maintain its population and genetic diversity.

Care

When caring for Weingartia trolli rosa, it is essential to replicate its native environmental conditions as closely as possible. Provide bright, indirect sunlight and a cactus potting mix that offers excellent drainage. Water the plant sparingly, allowing the soil to dry out completely between waterings to prevent root rot. During the dormant winter months, reduce watering to a minimum. The cactus benefits from being in cooler environments in winter but should be sheltered from frost. Fertilize during the growing season with a balanced, water-soluble cactus fertilizer to encourage blooms and growth. Regular monitoring for pests like mealybugs and spider mites will help maintain the health and beauty of your Weingartia trolli rosa.
