Report an issue with this species

Populus tremuloides, also known as quaking aspen, is a deciduous tree native to cooler areas of North America. It is recognized for its tall trunks, smooth pale bark, and glossy green leaves that turn golden in autumn and 'quake' in the slightest breeze. This species forms large clonal groves through its root system and is the most widely distributed tree in North America.
