Origin of Name:
The cultivar Sulcorebutia canigueralii owes its name to the Spanish botanist Miquel Canigueral (1897–1989), who extensively studied and collected cacti during the mid-20th century in South America. The genus name "Sulcorebutia" is derived from Latin roots: "Sulco" meaning “furrow” or “groove,” and "Rebutia," a tribute to Swiss botanist Pierre Rebut, highlighting its historical taxonomic roots. The species "canigueralii" specifically honors Canigueral’s efforts and discoveries made during his expeditions, emphasizing his contributions to South American cactus botany.
This cultivar designation highlights the plant's heritage and connection to one of the prominent figures in cactus exploration, while "cultivar" signifies its cultivated, selectively bred nature to enhance ornamental qualities like flower color, size, and form.
Origin of Plant:
Sulcorebutia canigueralii cultivar originates from the high-altitude regions of Bolivia and Argentina, where it naturally grows on rocky, well-drained slopes and mountain sides. It was discovered during botanical expeditions in the mid-20th century focused on cataloging South American deserts. Its natural habitat includes harsh, arid environments characterized by intense sunlight, low rainfall, and rocky terrain—conditions that this resilient plant has adapted to remarkably well.
This particular cultivar was developed through selective breeding by cactus growers in Europe and North America, aiming to enhance its visual appeal, especially its vibrant blossoms and compact growth habit. Its cultivation history is rooted in the ongoing tradition of horticulturists striving to create striking and easy-to-care-for ornamental cacti.
Description:
This charming cactus features a dense, globular to short columnar shape, typically reaching 4-8 inches tall with a width of about 3-6 inches. Its surface is characterized by evenly spaced ribs adorned with woolly areoles from which radiate a dense array of white or yellowish spines, creating a soft yet striking appearance.
The highlight of Sulcorebutia canigueralii cultivar is its vibrant, show-stopping flowers—large, star-shaped blossoms in rich, fiery red or pink—appearing in spring and summer. These flowers often have a hint of orange or yellow at the center, providing a warm, inviting contrast to the greenish body. The blooms are fragrant and long-lasting, adding spectacular visual appeal to the plant.
This cultivar is popular for its gorgeous floral display, compact form, and unique coloration, making it a favorite among cactus collectors and enthusiasts seeking eye-catching ornamental plants.
Conservation Status:
As a cultivated cultivar, Sulcorebutia canigueralii is widely propagated through seed and cuttings, with no current threat to wild populations. Its rising popularity and responsible cultivation practices have helped preserve its genetic diversity. Naturally, wild populations of related species face habitat loss and overcollection, so responsible sourcing from reputable nurseries is encouraged to maintain sustainability.
Care:
Sulcorebutia canigueralii cultivar thrives with plenty of direct sunlight—preferably 4-6 hours daily—to bring out its vivid coloration and promote flowering. Use a well-draining cactus or succulent soil mix, ideally with added sand or grit to prevent water retention. Water sparingly—allow the soil to dry out completely between waterings—and reduce watering in winter to once a month or less, especially if kept indoors.
This cactus prefers warm temperatures between 70°F to 85°F (21°C to 29°C) and is not frost-tolerant; protect it from freezing temperatures and frost during colder months. It benefits from good airflow and should be kept out of overly humid environments. Fertilize during the growing season with a diluted cactus fertilizer once a month for optimal health and blooming potential. With minimal care, this plant will reward you with its dazzling flowers and attractive form year-round.
