Berberis thunbergii ‘Kobold’
Deciduous, Shrubs, Decorative fruit or berries
These dense, spiny-stemmed plants, especially the deciduous species, tolerate climate and soil extremes. Require no more than ordinary garden care. Each year, thin out oldest wood and prune as needed to shape—after bloom for evergreen and semievergreen types, late in the dormant season for deciduous kinds. They make attractive hedges. Informal style is best for species grown for spring flowers (yellow, unless otherwise noted) and ensuing berries, which are borne on previous year’s growth; species grown for foliage can be sheared. To rejuvenate overgrown or neglected plants, cut them to within a foot of the ground before new spring growth begins.
Closely related to and sometimes grouped by botanists with Mahonia.
Japanese native hardy to –20°F/–29°C. Graceful habit with slender, arching, spiny branches; if not sheared, usually reaches 4–6 ft. tall with equal spread. Densely covered with roundish, 1/2–1 1/2-in.-long leaves that are deep green above, paler beneath; leaves turn yellow, orange, and red before they drop in autumn. Beadlike bright red berries stud branches in fall and through winter. Use as hedge, barrier planting, or specimen shrub. Many attractive varieties are grown for their vivid foliage color.‘Kobold’
