Chinese Wingnut

Pterocarya stenoptera (ter-oh-KAIR-ee-ah sten-OP-ter-uh)

Family: Juglandaceae Non-native Canopy (>40 ft)

Large pendulous shade tree in the walnut or Juglandaceae family. Dappled shade; expansive roots on soil surface; tough dependable tree; strong wood. This tree is similar to Pterocarya fraxinifolia (Caucasian wingnut) except the midribs (rachis) of its compound leaves have toothed, often serrate wings. New foliage is downy and young twigs are covered with tawny down. Non-showy yellow-green fall leaf color but brown wingnut fruits are showy in the fall. Seasons of Interest: Nut: Fall Insects, Diseases, and Other Plant Problems: No serious problems but is considered high maintenance because fruits, foliage and twigs often produce a significant amount of litter. Form: Pendulous branching; open canopy; some times multistemmed; spreading branches
