Cobnut

Corylus avellana 'Kentish Cob'

fruit

Kentish Cob is a premium hazelnut cultivar producing larger, sweeter nuts than wild hazel in a more compact growth habit. This improved variety requires cross-pollination from compatible pollinators and benefits from regular pruning to maintain productivity. It combines good nut quality with ornamental interest from early spring catkins.
