Description
Frailea castanea is a charming miniature cactus prized for its perfectly rounded shape, rich chocolate-brown to olive-green colouring, and finely textured ribs. Native to South America, this compact species is ideal for collectors who appreciate small cacti with unique character. Its slow growth and neat form make it a perfect choice for windowsills, miniature landscapes and specialist cactus collections.
Despite its tiny size, Frailea castanea can produce surprisingly large, bright yellow flowers during the growing season. Like many species in the genus, it often self-pollinates, producing seeds even if the flowers open only briefly or remain partially closed.

Good to Know
The name Frailea honours Spanish naturalist Manuel Fraile, while the species name castanea refers to its attractive chestnut-like colouring.
