Populus tremuloides “Quaking Aspen” Salicaceae

This adorable Quaking Aspen sapling had lost all but three of its leaves by the time I photographed it in early October. While Quaking Aspen is famous for its adventitious, clonal reproduction, this little guy probably grew from seed because it was all alone in the at the edge of a stand of conifer saplings. Seedlings in the genus Populus are often the first to colonize abandoned mining sites that are too toxic for other species. Recent research suggests that they are only capable of this feat because of a mutualistic relationship with various species of mycorrhizal fungi such as these earthballs.
