Very attractive small, deciduous and shrubby tree. Deep purple leaves and purplish catkins and edible nuts in the autumn. Corylus maxima purpurea in fully hardy, robust, easy to brow and pretty much pest and disease free. Full sun will produce the most dramatic dark leaf colouring. Cut back in spring to control size if desired. Height: ultimately up to 6m without cutting back - we keeps ours at no more than 2m height.
