Summer Quaking Aspen . . . . (Populus tremuloides) Native to North America.

Quaking Aspen is known for its graceful leaves which flutter
like the tresses of a shy river goddess at the slightest hint of wind.
This shimmering movement is caused by the leaves’ flattened petioles
(literally, ‘small foot’ or the leafstalk that supports the blade of a foliage
leaf, usually round, but sometime flattened, or even winged). It is the
most widely distributed tree in North America, and grows as a solitary
trees or multi-stemmed clones over more than 100 degrees of longitude
and nearly 50 degrees of latitude.
