How to grow

Cultivation Grows well in most soils but dislikes shallow chalky soil. Requires full sun and a well-drained sandy soil in coastal plantings but it requires shelter from cold drying winds when planted inland

Propagation Propagate by semi-hardwood cuttings in summer or hardwood cuttings in winter. Propagate by seed sown, when ripe, in containers in a cold-frame

Suggested planting locations and garden types Low Maintenance Coastal
