Berberis japonica is a species of flowering plant in the family Berberidaceae, native to Taiwan. [2] 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.

Description

It is an evergreen shrub growing to 2 m (7 ft) tall by 3 m (10 ft) wide. [4] The foliage is pinnate, glossy dark green above, paler beneath, and sharply toothed. Each leaf usually has six to eight pairs of leaflets together with a single terminal leaflet. The plant produces new shoots regularly from the base, so it is clothed in foliage at all levels.

The small, scented, yellow flowers are borne from autumn through winter into spring. The inflorescences are 25 cm or more long, at first arching and then pendant. Blue or black fruits develop in spring and summer. [2] [5] [6] [7] [8]

Taxonomy

Berberis japonica was initially scientifically described and named by Carl Peter Thunberg as Ilex japonica in 1784, believing it to be a true holly. [1] In 1821 Augustin Pyramus de Candolle reclassified it as Mahonia japonica. Disagreeing with this, Kurt Polycarp Joachim Sprengel classified it in Berberis as Berberis japonica in 1825. [1] A paper was published by Joseph Edward Laferrière in 1997 summarized the arguments for Mahonia being more properly classified as a synonym of Berberis. [9] As of 2023 this is the most common classification by botanists. [1]

Cultivation

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. [10] [11] 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'. [12] A hybrid with Berberis napaulensis var. napaulensis (M. siamensis), called Mahonia × lindsayae 'Cantab', though less well known, is a useful garden plant [13] and also holds an Award of Garden Merit. [4]

Berberis bealei, native to mainland China [14] and also widely cultivated, is usually treated as a separate species, but in the past has been listed as a cultivar of Berberis japonica. [3] Its most obvious differences from B. japonica are in shorter, upright flowering racemes and wider leaflets.

<i>Berberis</i> Genus of flowering plants representing the barberry family

Berberis, commonly known as barberry, is a large genus of deciduous and evergreen shrubs from 1–5 m (3.3–16.4 ft) tall, found throughout temperate and subtropical regions of the world. Species diversity is greatest in South America and Asia; Europe, Africa and North America have native species as well. The best-known Berberis species is the European barberry, Berberis vulgaris, which is common in Europe, North Africa, the Middle East, and central Asia, and has been widely introduced in North America. Many of the species have spines on the shoots and all along the margins of the leaves.

Berberis nervosa, commonly known as dwarf Oregon-grape, Cascade barberry, Cascade Oregon-grape, or dull Oregon-grape, is a flowering plant native to the northwest coast of North America from southern British Columbia south to central California, with an isolated population inland in northern Idaho. It is especially common in second growth, Douglas-fir or western redcedar forests, making use of those pools of sunlight that intermittently reach the ground.

<i>Berberis repens</i> Western North American species of barberry

Berberis repens commonly known as creeping mahonia, creeping grape holly, or creeping barberry, is a species of Berberis native to most of the western United States and two western provinces of Canada. It is low growing shrub that spreads by underground stems. As a species it is well adapted to fire and is a very common understory plant in western forests. An evergreen species, it provides food to deer and elk in winter and can make up a significant part of their diet. The berries are eaten by birds and small mammals, aiding it in spreading to recently disturbed areas. It has found use as a xeric ornamental plant and has escaped from cultivation in areas beyond its native range.
