Description: Habit Clumping globular cactus, up to 7 cm in diameter up to 10 cm tall. It can grow in clumps 10-15 cm wide. The especially notable characteristics of this cactus are its dark stem colour, emphasized by the small, white areoles, and its large, intensely red, yellow-throated flowers reminding one of red daisies.
Stem: Up to 5 cm Globose, dark green, that begins to offset in about its third or fourth year, eventually to make a moderately tight clump with the individual stems standing out a little on their own.
Tubercles: In two downward spirals, in ratio 8:13.
Spines: Small, snow-white, very thin, very short, and soft, but can still poke.
Flowers: A larger crop of pure white flowers, 3.5 cm wide, develops from the base of each head, resulting in a superb display at mid season.
Blooming season: It is usually one of the earliest rebutias to bloom in spring.

Cultivation and Propagation: Full sun to light shade. Water regularly in summer, but do not over-water. Keep dry in winter. Hardy to -4°C.
It is better that they be repotted regularly. Repotting will increase the number and size of stems, and will increase the number of flowers produced. Repot yearly until they reach about 100 mm in size, then every two or three years will suffice. Repotting is best done at the end of winter, but it can be done at other times, too. Do not water for a couple of weeks after repotting, to reduce the risk of root rot via broken roots.
Propagation: Offsets, seeds
