Juglans regia 'Purpurea'

Fruit Edible Trees

A slow-growing, small deciduous tree with a round, irregular crown to around 5m in height. Young branches emerge purple-red, turning to pale grey and furrowed, like the bark. Segmented leaves emerge glossy red, turning to a more matt purple-red during the summer. Flowers are reddish brown in spring, followed by red fruits but these fruits are not produced in any great number. A better variety for smaller gardens but more appropriate as an ornamental rather than crop-bearing tree
