General Description

At first glance, the hybrid Ottawa barberry looks like a Japanese barberry on steroids. Ottawa barberry shows intermediate characteristics of both of its parents: European barberry (Berberis vulgaris) and Japanese barberry (B. thunbergii)). It develops into a taller, rounded deciduous shrub.

Rounded oval leaves, sometimes with tiny teeth on the edges, are found on the Ottawa barberry. The leaves are medium green, turning haphazardly yellow to orange-red each autumn. In spring, clusters of pale yellow flowers edged in red dangle from the spiny twigs. After bee pollination, the flowers produce small oval red fruits.

Grow Ottawa barberry in full sun to bright dappled shade. It prospers in any moderately fertile soil that is moist but well drained. Use this deciduous shrub as a screen or barrier shrub to prevent trespassers on a property, or to help keep animals within a zoned area.

Typically, smaller-maturing and more ornamental purple-leaved selections are grown in garden settings. Examples of Ottawa barberry cultivars include 'Silver Miles' and 'Superba'.
