About
Berberis japonica is a species of flowering plant in the family Berberidaceae, native to Taiwan. Despite the name, it is not native to Japan, though it has been known in cultivation there for centuries. The wild origins of this species have long puzzled botanists, but wild plants in Taiwan, previously known under the name Mahonia tikushiensis, appear most similar to the cultivated forms of B. japonica.
How to grow it
The plant is much grown as an ornamental shrub, and for use in landscapes. It is of value for its bold foliage, flowers in flowering season, and as a groundcover landscape shrub. Its spiny foliage invite use in security hedging.
Berberis japonica has received the Royal Horticultural Society's Award of Garden Merit. The hybrid between it and Berberis oiwakensis subsp. lomariifolia is also a popular garden plant. Known as Berberis × hortensis, several cultivars have been developed from it, including 'Charity', 'Winter Sun' and 'Lionel Fortescue'. A hybrid with Berberis napaulensis var. napaulensis (M. siamensis), called Mahonia × lindsayae 'Cantab', though less well known, is a useful garden plant and also holds an Award of Garden Merit.
