filbert 'Gunslebert'
A large shrub, potentially to 6m if unpruned, with broad, rough leaves and yellow-brown catkins in late winter or early spring, followed by clusters of nuts in pale green husks in early to mid-autumn. This filbert produces good yields of large, well-flavoured nuts from an early age but crops better if pollinated by a different variety
