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