How to Grow

Cultivation

Tolerant of a range of soils and locations, but grows best in any well drained soil in full sun or partial shade, though flowering and fruiting are best in full sun. See berberis cultivation for further advice

Propagation

Propagate by seed sown in a seedbed in early spring. See trees and shrubs from seed. Many Berberis species cross freely in gardens, so seed-raised plants are often hybrids. Take semi-ripe cuttings in summer
