Also called the Trembling Aspen or White Poplar, the Quaking Aspen has one of the largest natural ranges of any tree in North America. Growing exceptionally vertically, the aspen reaches 60' tall with a spread of less than 10'. Their trunks are pale white in color whereas their leaves turn a brilliant yellow in autumn. Aspen trees grow through root shoots- sending smaller tree out concentrically creating entire groves of genetically identical trees. The largest organism on earth is a Quaking Aspen in Utah called Pando.
