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. This is a male cultivar so it doesn't produce berries

Propagation

Propagate by semi-ripe cuttings in late summer
