Pterocarya stenoptera – Chinese wing nut

View prices and availability
Usually grows branches low down and forms a dense crown with several heavy main branches. Because of the low branching and widely spreading lateral branches old specimens are sometimes broader than they are tall. Old trunks are dark grey and deeply grooved. The dark greenish-brown twigs carry a great many lenticels. The hairless leaf buds are on short stems. Young emerging leaves can be damaged by a late night frost but recover easily. The large pinnate leaves consist of 13 to 21 (sometimes 25) lanceolate leaflets. These are 4 - 10 cm long. The leaf stem has prominent wings. The round to ovoid nutlets have two narrow wings. The pendulous fruit catkins remain on the tree during the winter months. Forms root suckers only when the tree is in a bad condition. Resistant to long-lasting flooding. Cannot take sea wind.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from November 2025.
