Bigtooth Aspen is a native short-lived deciduous tree growing 30 to 60 feet high with a diameter of 1 to 1-1/2 feet, an irregular thin crown and a straight trunk with gently ascending branches. It seldom exceeds 60 feet in height and 20 inches in diameter. Notes: Bigtooth Aspen is indigenous to the Garden. 3 0 obj Heritage Tree: Just SE of the Garden's front gate is a large Bigtooth Aspen listed as a Minneapolis Heritage Tree for its champion size of 58 feet in height and 30 inches in circumference.

Above: Bigtooth Aspen bark - 1st photo - younger branches; 2nd photo - the lower trunk with age begins to scale and create ridges; 3rd photo - the lower trunk of old tress is furrowed and ridged. 3rd photo - Twig- buds in spring on an older twig. Bigtooth aspen can be distinguished from quaking aspen by the smaller number and the larger size of the teeth on the leaves and from the lighter colored buds. A single catkin can have 70 to 100 capsules.
P. grandidentata is strongly heterophyllous, that is, it has two types of leaves - those that are formed in the winter bud for early spring growth, known as preformed or early leaves and leaves produced later in the season known as neoformed leaves. Flowers are in dense 2 to 3 inch long brownish fuzzy drooping catkins. The bark is thin, smooth, and whitish, gray or olive-green to milky-brown on young stems becoming a darker gray-brown and furrowed into flat, scaly ridges with diamond shaped lenticels and splits on older trunks. Bigtooth aspen and quaking aspen (P. tremuloides) are the only two North American aspen species. The overwintering large terminal bud has fine fuzzy hair. usually larger than other Populus species, coarsely toothed with a flattened slender leafstalk (petiole), young leaves whitish and woolly underneath, Produces more wood per acre than most other trees.
