Water sparingly from March until October, and keep perfectly dry in winter, at temperatures from 5 to 15 degrees centigrade. (but it is Hardy to -7C for short periods).  In the rest period no high atmospheric humidity!! Sun Exposure: Light shade to full sun.


Propagation: Almost exclusively by seed. Plants are sometimes grafted onto column-shaped cacti.
