How to grow

Cultivation Grow in fertile, moist but well-drained soil, in full sun - will grow in partial shade, but the leaves will be most colourful and wood will ripen better in an open sunny position. Grow in the open in milder areas and in coastal gardens with shelter from the worst cold, drying winds, while in colder gardens grow in a sheltered position such as a south- or west-facing wall, and protect roots in winter with a deep dry mulch

Propagation Propagate by semi-ripe basal cuttings in summer, by basal hardwood cuttings in late autumn, or by layering or air layering in spring
