The Norway maple was first introduced to North America from Europe by botanist John Bartram in 1776. He established the tree by selling seeds and seedlings throughout the Northeast. Norway maple was planted by the thousands in the 1930's as a replacement for American elms killed by Dutch elm disease. It has become one of the most common but, unfortunately, most invasive trees that disrupts native forest regeneration. The tree grows to 70 feet and can be 50 feet wide.
