General tree description
Pterocarya x rehderiana is a hybrid of the Causasian and Chinese wingnuts, Pterocarya fraxinifolia and Pterocarya stenoptera. It is a large and fast-growing tree, up to around 25 metres tall, often with a short trunk and a very broad crown. Its bark is grey and closely ridged, and the leaves are pinnate, 20cm or more long, with eleven to twenty-one leaflets. The leaflets are 5 to 10cm long, ovate in shape and serrated, dark green in summer, turning butter yellow in autumn. In spring there are attractive long, drooping, catkins with tiny white or light green flowers. These are followed in early summer by small, green-winged nutlets in long, drooping strings. The nutlets mature to brown in late summer or autumn.
