Aspen
( Populus tremuloides )
The quaking aspen gets its
name by their distinctive leaves
that quiver in the slightest breeze.
The quaking aspen is a narrow
tree with a smooth and greenish-
white bark that grows up to 20 to
60 feet tall.
This deciduous tree has flowers that have male
and female catkins on separate trees. Male catkins
are small, 3/4 to 11/4 inches long, and the female
catkins are larger, 11/2 to about 4 inches long.
The leaves are approximately 1 to 3 inches long,
which are smooth
and round
to triangular-shaped. They are dark green on
the top, with a paler underside, which turn
golden yellow or red in the fall. The fruit
consists of tiny capsules covered with cotton-like
down.
The quaking aspens grow throughout North America
and grows best on moist, well-drained soil rich
in calcium (limestone based).
