The bark is smoot, white and has black scars where branches once were. Unlike our native birch, it does not peel.
Leaves are nearly circular, heart shaped. They have flat stalks that tremble in the wind, giving the plant its Latin and common name. The leaves turn a brilliant yellow in the fall.
Flowers are dangling catkins that appear before the leaves.
Aspens grow from low to subalpine elevations in a variety of soil types. They are very shade tolerant. They reproduce mainly from root suckers.
Historically they have been made to make canoes, tent poles and drying racks. They are an important habitat for beavers and birds. Current uses include wood products: pulp, flakeboard, veneer, matches, plywood and chopsticks. The wood does not splinter, making it good for benches. --------------------------- You are looking for a small round tupperware. It is big enough for a TB, but not much else. I've started it with a spider and some beads. BYOP.
Note: I do check my cache log books. No signature = no find.
