Botanical Name: Rebutia brunescens
Common Names: Bolivian Crown Cactus, Brown Rebutia, Crown Cactus, Dwarf Rebutia
Rebutia brunescens is a small, clumping cactus native to Bolivia, admired for its dark green to bronze-toned stems and vivid, showy flowers that bloom freely in spring. This miniature species forms rounded heads that offset readily, creating dense clusters over time. Its compact size and reliable flowering make it a favorite for windowsills, small containers, and cactus collections. Mature plants typically stay under 6 inches tall, spreading wider as they clump.
Care and Cultivation:
Prefers bright light to full sun
Water sparingly; allow soil to dry completely between waterings
Use a fast-draining cactus soil mix
Ideal for small pots and indoor growing
Frost Tolerance and Cold Hardiness:
Best suited for USDA Zones 9–11
Can tolerate brief cold down to about 25°F (-4°C) when dry
Protect from frost and prolonged cold
Ideal growing temperatures: 60–85°F (16–29°C)
Winter Dormancy and Health:
Growth slows during winter
Reduce watering significantly in colder months
Cool, dry winters encourage better flowering
Maintain bright light year-round
Notes:
Darker stem coloration compared to many Rebutia
Produces bright, showy spring flowers
Offsets readily to form clumps
Compact and beginner-friendly
