Berberis thunbergii RUBY CAROUSEL (syn. ‘Bailone’) – Japanese Barberries are thorny deciduous shrubs grown for their brightly coloured foliage. RUBY CAROUSEL was introduced by Bailey Nurseries and features glossy reddish-purple leaves that colour best in full sun. It has insignificant yellowish flowers in spring. Grows 3-4’+ high by 3′ wide. Hardy to zone 4.
Berberis thunbergii GOLDEN NUGGET (syn. ‘Monlers’) – This Japanese Barberry features tiny leaves of bright gold that form a compact, dense shrub. The yellow spring blooms are insignificant and often hidden in the foliage – these are followed by tiny red berries in early fall. GOLDEN NUGGET is both deer and rabbit resistant.

Berberis thunbergii ROYAL BURGUNDY (syn. ‘Gentry’) – An improved form of ‘Crimson Pygmy’ selected by Leo Gentry Sr. The new growth is reddish maturing to deep burgundy and is often contrasted by green leaves nestled in the crown. The autumn colour intensifies to reddish-black and it makes a good informal hedge. Grows 2′ high by 3′ wide. Hardy to zone 4.
Berberis thunbergii SUNSATION (syn. ‘Monry’) – Another of the gold-leaved Japanese Barberries which may take on hints of lime green at maturity or when planted in partial shade.

Hardy to zone 4.

It is a low maintenance plant that can be grown in containers or used in the mixed border for contrast. The foliage shifts to a burgundy-red in autumn. Deer resistant. Grows 1-2′ high by 2′ wide.
