Where is Alder tree found?

Alder is native to central Europe and has since spread to Russia, Siberia, Asia, Canada, the United States, and other parts of the world. Within America, alder trees are found in the Northwest, Midwest, and Northeast, with the greatest number located in West Virginia and Maryland.

It’s estimated that 20%-70% of people allergic to alder also have oral allergy syndrome, a type of food allergy that develops after a pollen allergy.
