Propagation
Sow fresh seeds during spring in flats and maintain a temperature of 19º to 27º C. (66º to 81º F). Prick out when large enough to handle and pot up.

Divide offsets during spring   and place in a container or plant in situ.

Take leaf cuttings from spring to summer and placed in a protected environment until roots appear, then pot up.
