Populus tremuloides
Quaking Aspen

The common name of Populus tremuloides is derived from the tendency of the leaves to tremble (quake) in the wind, or even light breezes, due to flattened petioles. This is a fast-growing and short-lived species that regenerates from root suckers and can quickly recolonize disturbed sites. Generally, most of the specimens in a grove of P. tremuloides are clones, all originating from the same stem. This plant is dioecious, so groves are usually all male or all female. The narrow-crowned Quaking Aspen tends to grow straight up and then lose its lower limbs over time. This species is not generally recommended for ornamental use due to its susceptibility to a number of pests and diseases. Prefers cooler climates.
