Rebutia minuscula
Easy · Beginner friendlyAbout Red Crown Cactus
Red Crown Cactus is a tiny clustering cactus from northern Argentina, forming colonies of green flattened-globular heads only 1-2 inches across. Despite its diminutive size, it produces a stunning ring of bright orange-red trumpet-shaped flowers each spring that often hide the plant entirely beneath a wreath of color. Easy to grow and reliably free-flowering even on small windowsills, it is one of the most beloved beginner cacti among American collectors.

History
Rebutia minuscula, commonly called red crown cactus, is a tiny globose cactus endemic to the mountains of northwestern Argentina in the provinces of Tucumán and Salta at 1500-2500 meters elevation. German botanist Karl Moritz Schumann described the species in 1895 and established the genus Rebutia to accommodate it, naming it after Pierre Rebut, a 19th-century French cactus dealer. The epithet minuscula means very small, referring to the diminutive flattened globose stems only 3-5 cm tall and 5-7 cm wide that readily offset to form dense clumps 15-20 cm across.
The dark green stems are covered with small spirally-arranged tubercles bearing areoles with 25-30 short white radial spines. In spring the plant produces a dense ring of brilliant red, orange, or rarely yellow funnelform 3-4 cm flowers arising from near the base of the stem—each flower is nearly as large as the stem itself.
The species has been a cornerstone of beginner and windowsill cactus collections since the late 19th century. Native to the high Andes of Tucumán, Argentina at elevations above 3,000 meters. Its tolerance of cooler temperatures and reliable flowering made it a fixture of mid-20th-century European cactus collections that crossed to the United States.
