Large-Tooth Aspen Care

Populus grandidentata, commonly called large-tooth aspen, big-tooth aspen, American aspen, Canadian poplar, or white poplar, is a deciduous tree native to eastern North America. The name Populus is from the Latin for poplar, and grandidentata refers to the coarse teeth on the leaves (grandis meaning "large", and dentata meaning "toothed").

Populus grandidentata is a medium-sized deciduous tree native to North America, found mostly in the northeastern United States and southeastern Canada. Leaves are similar to Populus tremuloides, but slightly larger and having larger teeth.

The leaves tremble in the wind as P. tremuloides does. Bark of younger trees is olive-green, thin and smooth; after 30–40 years, the bark is gray, thick and rough with grooves.

Bigtooth aspens are dioecious, medium-sized deciduous trees with straight trunks and gently ascending branches. Heights at maturity are around 60–80 feet (18–24 m) with diameters of 8–10 inches (20–25 cm). They are fast growing and are relatively short-lived; stands will begin to deteriorate after 60–70 years, while individuals can live up to 100 years. They often constitute early successional species of their landscapes. Roots are shallow and wide spreading; lateral root growth in a forest may be as far as 60 feet (18 m). Generally, four to five lateral roots originate from the tree, and then branch within 2 feet (60 cm); vertical, penetrating roots near the base anchor the tree.
