The shape of Quaking Aspen leaves is described as round-triangular.
Quaking Aspen, also known as quaking poplar, is easily recognized by several distinct characteristics, notably its unique leaf shape and movement.
Key Characteristics of Quaking Aspen Leaves
Based on observations, the leaves of the Quaking Aspen possess a specific form and behavior:
- Shape: The primary characteristic is their round-triangular shape. This distinct form helps in identifying the tree.
- Movement: These leaves are known for their ability to twist on their petioles (the stalk that attaches the leaf to the stem).
- Trembling/Shimmering: Due to the way they attach and twist, the leaves tremble and shimmer readily, even with the slightest breeze. This movement is the origin of the "quaking" name.
- Fall Color: In the autumn season, these leaves transform into a vibrant, blazing yellow color.
The combination of their specific shape and dynamic movement makes the Quaking Aspen a visually striking tree, particularly when its leaves are in motion or displaying their fall colors.
