Trembling aspen is found throughout Prince Edward Island. It is not a large tree, averaging about 40 feet in height and 8 to 10 inches in diameter, when mature.The trunk is slender, with a gradual taper, and extends almost to the top of the tree. The moderately stout crown is round-topped and open. Poplar, as it is called here, grows best on a well-drained loam, but is found on a wide variety of soils. It will not grow in the shade of other trees and occurs frequently in pure stands, or mixed with white birch, pin cherry, large-toothed aspen. It reproduces very quickly and easily by means of root suckers.
