How can you identify an aspen? It’s easy! Just look for the leaves. The leaves of an aspen are unique because they are a different color than any other type of leaf in the forest. They are also flat, and often found in clusters on one side of the tree trunk.
Aspen trees come in many different shapes and sizes. Some grow to be thick and sturdy, while others are thin with a more delicate appearance. There are eight different species of Aspens that grow in the United States, each with its own unique characteristics. The most common is “quaking” aspen (also known as trembling or white) which has leaves that turn yellow-orange in autumn before dropping off completely for winter. You can identify this species by looking at the bark – it’s smooth and grayish-white when young, but becomes furrowed with age and darkens to a light grey color.

The other two types of aspens are “broad-leafed” or red aspen and “balsam,” also known by its scientific name, Populus balsamifera. In general these trees have a more densely canopied shape than quaking aspens which tend to be wide at their base but narrower near the top.”Broad-leafed” is characterized by broader leaf blades with an overall darker hue that stays green all year round (but may turn yellow when very old). The bark on this species appears smoother than white and grayish-brown when young, then becomes furrowed with age. Balsa m’s bark starts out smooth before developing gray and white flecks.
Aspen leaves are often called “trembling” or “shaky.” This name originates from how the leaves seem to vibrate in the slightest breeze. The other two types of aspens are broad-leafed, also known by its scientific name, Populus balsamifera; and Balsa m which is characterized with a smoother bark that becomes furrowed when old. Broad-leaved has broader leaf blades with an overall darker hue that stays green all year round (but may turn yellow when very long). These trees have are more densely canopied shaped than quaking Aspens which usually tend to be wide at their base.
The leaves of both broad-leafed and quaking aspens are arranged in pairs on either side off the twig, so they resemble a heart when seen from above. Balsa m’s leaves are different – they grow at odd angles to the stem with each pair of leaves appearing as if it is one leaf that has been dissected down its length into two parts. The bark tends to be slightly furrowed or wrinkled and brownish gray in color which you can see this very best near where branches meet the trunk. Like other Aspen trees, balsam poplar (broad-leaved) develops a prominent circular pattern of rings called annuli just under their bark layer because these trees do not produce sap.
Aspens can be found in many parts of the world, but North America is home to a wide variety. The species that you are most likely to see growing throughout eastern Canada and much of the northern U.S. goes by several different common names depending on where it grows: quaking aspen, trembling aspen, white pine, or mountain maple (in some areas). These trees have pliable branches which allow them to move with even strong winds without breaking off because they bend instead of snapping at their point of connection like other types do when they break or fall over – hence its name “quaking” aspen!
There are also two subspecies that grow primarily in western North America: bigtooth aspens and black aspens. Bigtooth species have very large leaves that are often over a foot long (this is what gives them their name) while the black ones have smaller, slightly fuzzy needles that grow in dense clusters on branches near the ends of skinny twigs; these can be used to distinguish between these two subspecies when you cannot identify which one it actually is.
There are other differences too: for example, bigtooth will also sprout cones from its trunk but not lower than about 40 feet above ground level whereas black aspen’s produce cones at virtually any height up to 66 feet! This means they need less space by spreading out more efficiently.
