The Pterocarya fraxinifolia, commonly known as the Caucasian Wingnut, is a deciduous tree native to the Caucasus region, including parts of Eastern Europe and Western Asia. This robust and attractive tree can reach a mature height of 20-30 meters, with a spread of 15-20 meters, making it a substantial presence in any landscape. Its broad, rounded crown and pinnate leaves with numerous leaflets give it a lush, textured appearance, often turning a vibrant yellow in the autumn.

One of the key features of the Caucasian Wingnut is its distinctive fruit, which consists of small nutlets attached to long, winged bracts, resembling miniature propellers. These bracts can be quite ornamental, adding visual interest to the tree even after the leaves have fallen. The bark is another notable feature, with its greyish-brown colour and ridged texture, adding to the visual appeal throughout the year.

The Caucasian Wingnut thrives in deep, fertile, and well-drained soils, preferring moist conditions but capable of tolerating short periods of drought once established. It grows best in full sun to partial shade, making it versatile for various landscape settings. Due to its size and preference for moist conditions, it is often planted near water features or in larger gardens and parks where it can fully showcase its grandeur. Its ability to adapt to different soil types and resilience in various environmental conditions make it a valuable addition to diverse planting schemes.
