I don't see this European species hardly at all in the Eastern or Midwestern USA. I do remember one good rounded specimen in northeast Illinois in a affluent neighborhood in the 1980's when I first was taking lots of plant photos for a class. European trees tend to not have as good a fall color as American or Asian trees. The native species in America are better in America.

Common Ash grows profusely in England, the seeds germinate much more readily than any of the other large trees in the UK. Very old trees can approach Oaks in size but is normally smaller than Oak or Chestnut trees, with a narrrow trunk, it grows a large canopy of fairly slender branches.

A native of Europe and Asia Minor, this tree likes soils on the alkaline side. The bark is pale grey and it has black leaf buds in winter. It often develops holes and fissures as it ages, making it a haven for wild life of varying types.
The leaves turn butter yellow briefly in the autumn. The fruits have a wing attached to aid dipersal and are known as 'keys' in England.
