Cultivars of Japanese Barberry: There are many cultivars available. Some of the more common ones are:

* Var. atropurpurea – The leaves assume reddish to purplish shades. The yellow flowers are tinged with purple, but the fruits are the same bright red as those of the species.
* Var. atropurpurea ‘Crimson Pygmy’ – This is the most popular Japanese barberry selection. This low, dense plant grows to 2 feet tall and 3 feet wide. The foliage color is best when grown in full sun.
* Var. atropurpurea ‘Rose Glow’ – The new leaves are rose-pink, mottled with deeper red-purple splotches. The colors gradually mature to a deep reddish purple. This variety has become extremely popular in the South. It grows to about 6 feet tall.
* ‘Aurea’ – The leaves of this dense, relatively slow-growing shrub are bright yellow. It does not flower or fruit heavily.
* ‘Kobold’ – Its habit is similar to that of a compact Japanese holly or boxwood. The shrub grows to 2 feet at maturity and forms a perfect mound without pruning.

* ‘Spring Glory’ is a selection with brilliant coloration to the new shoot growth. The leaves and stems are tinted red to bronze-red. Pruning this shrub is not recommended.
