Common Names: Big-tooth aspen, large-tooth aspen, American aspen, white poplar
A deciduous tree native to eastern North America with a straight trunk and gently ascending branches. Heights at maturity are around 18 to 24 m with diameters of 20 to 25 cm. Bark of younger trees is olive-green, thin and smooth; after 30–40 years, the bark is grey, thick and rough with grooves. Roots are shallow and wide spreading; lateral root growth in a forest may be as far as 18 m. Generally, four to five lateral roots originate from the tree, and then branch within 60 cm; vertical, penetrating roots near the base anchor the tree. The species is able to adapt to a wide range of soils, though it is most abundant on sands, loamy sands and light sandy loams. Big-tooth aspens can tolerate sandy uplands and high, rocky sites.
