Stan’s Notes: The most widely distributed tree in North America. Leaves catch gentle breezes and shake or quake in wind. Also known as Trembling Aspen or Popple. Grows in large, often pure stands. Returns from roots if cut or toppled. Most reproduce by suckering off their roots, which creates clone trees. One stand in Utah–106 acres (42 ha) with about 47,000 trees–is the largest single living organism in the world. Has survived lab temperatures of -314 °F (-192 °C).
