Best grown in moderately fertile soil, in a sunny and sheltered position. It is heat tolerant, and once established, fairly drought tolerant, too. Not well suited to wet, poorly drained soils
Propagate by softwood cuttings, or sow seeds in cold frames
Cut back hard each spring, to within 2 leaf buds of old growth. Weak stems should be cut back to the base. There maybe some dieback in cold winters, cut back to the base in spring
