How to Grow

Cultivation

Grows best in neutral to slightly acidic or slightly alkaline, humus-rich, moist but well-drained soil. Plant in a warm sheltered position in full sun to encourage flowering. Can also be grown in pots. Feed in spring, with a slow-release, high potash formula, such as rose food, and mulch in autumn to help maintain soil moisture levels and suppress weeds.

Propagation

Propagate by softwood cuttings in late spring, by semi-ripe cuttings in summer, or by layering in spring or autumn.

Suggested planting locations and garden types

  • Coastal
  • Cottage and informal garden
  • City and courtyard gardens
  • Patio and container plants
  • Wall side borders

Pruning

Very little pruning required, especially in the first three years. After three years prune annually after flowering to maintain its shape and to help ensure the outer branches don't fall outwards - pruning group 1.

Pests

May be susceptible to aphids, scale insects, mealybugs and glasshouse whitefly when grown under glass

Diseases

May be susceptible to honey fungus (rarely) and powdery mildews
