An elegant and majestic tree, Pterocarya fraxinifolia is rarely encountered in gardens the UK, perhaps due to its widely spreading habit. Native to the lush river valleys of Iran and central Asia, it favours moist soil and plenty of light. This deciduous tree is a stunning sight during the late summer months, when covered in slender catkins, bearing distinctively winged nuts.

A hardy tree, Pterocarya fraxinifolia has a slight sensitivity to late frosts and is grown largely for ornamental purposes. It has a rare ability to form a large tree in a relatively short span of time and can grow to the size of a mature oak within just 25 years. Many specimens develop multiple stems, with several trunks branching from near ground level. Pterocarya fraxinifolia was first introduced to France from Persia in 1782 by André Michaux, a French botanist, who was later named the King’s Botanist and sent to North America to undertake extensive plant collections for his country. The species was introduced to Britain in the early 1800’s.
