Possibly more common in cultivation in north-west Europe than Caucasian Wingnut, but nonetheless, this species is not widespread. Introduced to Europe in 1860.

Native to China, Taiwan and Vietnam.

Monoecious. Wind-pollinated. Seeds wind- or water-dispersed.

Moderately tall (25m), vigorous, broad-crowned, often suckering. Bark grey-brown, deeply latticed. Twigs with naked buds. Leaves compound pinnate, 15-20cm, with 10-20 paired leaflets, usually lacking a terminal leaflet, on a rachis with distinct serrate wings interrupted by each leaflet pair. Male catkins 8cm; female 20-45cm, pendulous, maturing to small nuts each with a pair of short wings (1-2cm).

Tolerant of wet ground and heavy, even compacted soils. It grows vigorously in warm, sheltered positions. Like others in the genus it suckers vigorously, which can be a real nuisance if planted too close to buildings, paths or roads.

No notable associations where introduced.

Thousand cankers disease is a serious risk to this species and many others in , in Europe currently present only in Italy.

A graceful ornamental if its suckering can be tolerated.
