Corylus avellana ‘Contorta’ is a small hazel with contorted stems that stand out in winter against the clear blue sky. From late winter it bears golden-yellow catkins, before fresh green, twisted leaves appear. It’s ideal for growing in a mixed sunny border or front garden, where its winter structure can be fully appreciated. It’s also suitable for growing in a large pot. The twisted stems are useful in flower arranging. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
