Previously known as Mahonia lomariifolia and Berberis lomariifolia, this plant is a striking, evergreen shrub from China. The leaves’ resemblance to holly and the bunches of blue berries that appear in winter explain the plant’s common name ‘‘Chinese holly grape’’.
Several narrow stems can grow to a height of 3m-4m with symmetrical rosettes of thick, glossy, dark green leaves forming near stem ends, which look attractive all year long.
Beware the fierce spiky leaves and plant safely back from path edges away from passers-by. Planted as a hedge it will create an effective spiky barrier.
Mahonia oiwakensis subsp lomariifolia thrives in moist, well-draining soil. Grow in partial shade sheltered from strong winds. It is relatively low maintenance and resistant to pests and diseases.
Simply prune out large stems to maintain its size and encourage new growth.
Propagate via seed or semi hardwood cuttings in summer.
Labelled as Mahonia lomariifolia, this plant is flowering now in the Asian plant collection in the upper garden.
