Quaking aspen
Populus tremuloides
The most widely distributed tree in North America - a slender, cool-climate deciduous tree famous for nearly round leaves on flattened stalks that flutter ("quake") in the lightest breeze and turn brilliant golden yellow in fall. Smooth greenish-white bark whitens to chalky white with black warty patches as it ages. In the wild, aspens grow in clonal groves rising from one shared root system, so an entire grove can be a single genetic individual, all male or all female.
