How to grow

Cultivation

Grow in moderately fertile, well-drained soil in full sun. Pinch out growing tips to keep compact. Plants will die back as temperatures drop; a deep dry mulch may protect the rootstock from light frosts, but it is advisable to take cuttings to insure against winter losses, or plant in containers that may be moved indoors over winter

Propagation

Propagate by softwood cuttings in spring, and semi-hardwood cuttings of non-flowering shoots in summer
