Cultivation:
Full sun to light shade.  Water regularly in summer, but do not over-water.  Keep dry in winter.  Hardy to -4C.
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
