General tree description
Juglans nigra is a large tree (up to 35 metres tall) with a domed crown and very dark grey-black, deeply fissured bark. It has large, hanging, pinnate leaves up to 60cm long, with nine to twenty-three finely toothed leaflets. The leaves are a rich green colour, turning golden yellow in autumn. The fruits are nuts encased in 3cm thick green husks and they rarely ripen in Britain.
