Populus tremuloides is a deciduous tree native to cooler areas of North America. The species is referred to Quaking Aspen, Trembling Aspen, and Quakies, names deriving from its leaves which flutter in the breeze. The tree-like plant has tall trunks, up to 25 metres, with smooth pale bark, scarred with black. The glossy green leaves, dull beneath, become golden to yellow, rarely red, in Autumn. The species rarely flowers, often propagating through its roots to form large groves.

Its northern limit is determined by its intolerance of permafrost. It occurs across Canada in all provinces and territories, with the possible exception of Nunavut. In the United States, it can be found as far north as the southern slopes of the Brooks Range in Alaska, and it occurs at low elevations as far south as northern Nebraska and central Indiana.. In the western United States, this tree rarely survives at elevations lower than 1,500 feet (460 m) due to the mild winters experienced below that elevation, and is generally found at 5,000–12,000 feet (1,500–3,700 m). It grows at high altitudes as far south as Guanajuato, Mexico

Shrub-like dwarf clones exist in marginal environments too cold and dry to be hospitable to full-size trees, for example at the species’ upper elevation limits in the White Mountains. (Wikipedia)

  • Did you know the powdery white sustenance obtained by rubbing the aspen’s bark is a good sunblock for hikers who forgot to bring their tube of SPF 30? Mother nature is amazing.

  • Wow all this was very informative… And I am glad I read Suzis comment… Really good to know!
    Have a great day
