These plants need a minimum temperature of 13-15C. They prefer humus-rich, well drained soil and partial shade in the summer. Water regularly and freely when in full growth, less at other times. Provide support and, in summer, thin out stems at intervals; shorten all growths by half in spring.
Propagate by softwood or semi-ripe cuttings in spring or summer.
