Why don't I see Aspen trees in Philadelphia like in Colordado
I'd like to plant Aspen trees in my yard. Will it thrive in 19066?
Answer
Dear Gardener: The Aspen you see in Colorado is the Quaking Aspen or Populus tremuloides. It is a native tree in the high elevations of Colorado--6,000-12,000 feet elevation. It is hardy in our area (hard in zones 1-8) and should be able to live here.
