Rebutia fiebrigii

Rebutia fiebrigii, the orange crown cactus or flame crown, is a species of flowering plant in the cactus family that is native to exposed rocky plateaux in the Bolivean Andes, at altitudes of 2100-4000 m above sea level. It consists of a solitary ball some 15 cm in diameter, covered in tubercles and silky hairs, with brilliant orange daisy-like flowers. In time these balls multiply to form mounds.

A highly ornamental plant, this is a popular subject for cultivation in a well-drained, dry, sheltered location with plenty of sunlight, which does not freeze in winter. The cultivars 'Donaldiana' and the smaller 'Muscula' ('Little Mouse') have gained the Royal Horticultural Society's Award of Garden Merit.
