Step 1 : Introduction to the question " Why are aspen trees unique? "
...
One aspen tree is actually only a small part of a larger organism. A stand or group of aspen trees is considered a singular organism with the main life force underground in the extensive root system. In a single stand, each tree is a genetic replicate of the other, hence the name a “clone” of aspens used to describe a stand.
Aspens grow all the time—even in winter. Beneath the thin, white outer bark layer is a thin green photosynthetic layer that allows the tree to create sugars and grow when other deciduous trees would otherwise be dormant.
Trees reach 12-18 m in height. Open grown specimens have a profusely branched, globular crown; forest trees have long, cylindrical trunks with short, rounded crowns.
Aspen begin flowering around age 2 or 3 and by age 10 they are producing large seed crops. Male and female flowers are borne on separate trees and generally appear in April or May before leaf expansion.
