Populus tremula

Also known as Eurasian Aspen, European Aspen, Trembling Poplar

Eurasian aspens produce rounded, coarsely toothed leaves with laterally flattened petioles that flutter and hiss in the slightest breeze. Massive clonal colonies propagate via vigorous root suckers, allowing a single genetic individual to persist across centuries after wildfire or clear-cutting. In early spring, pendulous catkins bloom on separate male and female trees before the foliage unfurls, releasing millions of tiny seeds equipped with silky hairs for wind dispersal.
