Cultivation: 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 |

Description: 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.
