Culture

Noteworthy Characteristics

Berberis thunbergii, commonly called Japanese barberry, is a spiny, broad-rounded, deciduous shrub with obovate green leaves. It typically matures to 5' tall and as wide. Leaves (variably sized to 1 1/4” long) typically turn attractive shades of orange, yellow and red in fall.

Specific epithet honors Dutch botanist Carl Peter Thunberg (1743-1828) who reportedly identified this species in Japan in 1784.

Forma atropurpurea have red to purple-red foliage.

'Rose Glow' is a dense, deciduous cultivar which grows 3'-6' tall. First leaves are purple, but new shoots emerge as a rose-pink mottled with bronzish to purplish red splotches. Leaves are of variable sizes (.50" to 1.25" long). Many branched, reddish-brown stems have sharp thorns. Tiny, yellowish flowers appear in late April to early May, but are often hidden by the foliage and are not considered showy. Bead-like, bright red berries form in fall and often last through the winter. The berries are attractive to birds.

Problems

No serious problems. Some susceptibility to bacterial leaf spot, anthracnose, root rots, wilt, aphids, barberry webworm and scale.

Garden Uses

Japanese barberry forms an excellent barrier or hedge. It is also effective when planted in groups or as a specimen.
