How to Grow

Cultivation

Grow in moderately fertile, moist but well drained soil, in light to full shade; prefers acidic to neutral soils but will tolerate alkaline soils where there is plenty of humus. Plants may become chlorotic on poor, dry soil or in too much sun. These selected plants produce male flowers, which are larger and showier but do not produce berries

Propagation

Propagate by seed, sown in a cold frame in autumn, or sown outside in spring; by softwood cuttings of new growth in early summer and given bottom heat; by semi-ripe cuttings in a cold frame in late summer; or by layering
