This tree is to be found north east of the most northerly tennis court, on the corner of the lawn and beside the path. The Tree Register indicates that it is thought to have been planted in or after 1894, the year that Roath Park opened.[1] In October 2002 the crown of this tree suffered severe storm damage and had to be re-balanced by tree surgeons.

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.
