Pterocarya fraxinifolia - Deciduous - Caucasian Wing Nut, Caucasian Wingnut Page

Discover the majestic Pterocarya fraxinifolia, popularly known as Caucasian Wingnut, a standout specimen tree native to the regions stretching from the Caucasus to northern Iran. Flourishing in full sunlight and well-drained soils, this striking deciduous tree is adaptable to both moist and drought-prone environments, showcasing an impressive resilience even in hard, compacted terrains. Revered for its broad, expansive presence, the Caucasian Wingnut reaches heights of 30-60’, occasionally soaring to 90’, creating a stunning, rounded silhouette that can transform any landscape.

Its allure is magnified by the formation of small, green winged nutlets nestled within female catkins, which cascade into mesmerizing 20” lengths throughout the summer. These nutlets mature to a rich brown by fall, often adorning the tree well into winter, adding a unique visual interest. Comprising glossy, sharply-toothed leaflets, each pinnate leaf can span up to 18” long, although fall diminishes its green allure to a subtle yellow-green. Ideal for parks and large commercial landscapes, Caucasian Wingnut thrives best where its extensive root system and free-suckering nature have ample space to impress. With minimal pest or disease concerns, this remarkable tree offers a blend of grandeur, heritage, and adaptability to enhance vast outdoor spaces.
