barberry

The genus Berberis has dimorphic shoots: long shoots which form the structure of the plant, and short shoots only 1–2 mm (0.039–0.079 in) long. The leaves on long shoots are non-photosynthetic, developed into one to three or more spines:96 3–30 mm (0.12–1.18 in) long. The bud in the axil of each thorn-leaf then develops a short shoot with several normal, photosynthetic leaves. These leaves are 1–10 cm (0.39–3.94 in) long, simple, and either entire, or with spiny margins. Only on young seedlings do leaves develop on the long shoots, with the adult foliage style developing after the young plant is 1–2 years old. Many deciduous species, such as Berberis thunbergii or B. vulgaris, are noted for their attractive pink or red autumn color. In some evergreen species from China, such as B. candidula or B. verruculosa, the leaves are brilliant white beneath, a feature valued horticulturally. Some horticultural variants of B. thunbergii have dark red to violet foliage. The flowers are produced singly or in racemes of up to 20 on a single flower-head. They are yellow or orange, 3–6 mm (0.12–0.24 in) long, with six sepals and six petals in alternating whorls of three, the sepals usually colored like the petals. The fruit is a small berry 5–15 mm (0.20–0.59 in) long, ripening red or dark blue, often with a pink or violet waxy surface bloom in some species, they may be long and narrow, but are spherical in other species.
