What it looks like

Largetooth aspen is recognizable by its round but coarsely toothed margins with white fuzzy hairs on the underside. The buds are not sticky or fragrant like balsam poplar. Young bark is pale green to yellowish-gray, becoming dark gray and deeply furrowed with age. Largetooth aspen is a very fast-growing species, living to about 60 years old.

Where it is found

Largetooth aspen can be found throughout southern Ontario north to Temiskaming Shores and Sault Ste. Marie. A separate population grows near the Ontario-Minnesota border.

Planting Tips

  • Size: Up to 20 m tall
  • Moisture: Moist to dry
  • Shade: Intolerant of shade, prefers full sun
  • Soil: Adaptable

Since largetooth aspen is a short-lived species with a large, suckering root system, it is best planted in naturalized areas for easiest maintenance.
