Quaking aspen (Populus tremuloides) is a deciduous tree native to cooler areas of North America, one of several species referred to by the common name aspen. It is commonly called quaking aspen, trembling aspen, American aspen, mountain or golden aspen, trembling poplar, white poplar, and popple, as well as others.
Quaking aspen has the widest natural range of any tree in North America, spanning 47 degrees of latitude (equal to half the distance from the equator to the North Pole), 110 degrees of longitude (nine time zones), and elevations from sea level to timberline. It is also the largest living organism, growing in clones that reproduce primarily by sending up sprouts from their roots. And as far as the oldest…a clone in Minnesota has been estimated to be 8,000 years old! – Arborday.org
