Different Leaves of Poplar Trees - Aspen vs Cottonwood

Ahh I sure do love all these poplars blowing in the breeze during the summer, so here are a couple cool distinguishing features of some of the most common ones you’ll see around here - Black Cottonwoods and Trembling Aspen. The leaves on Black Cottonwoods are typically oval shaped, thick, waxy and durable with their chlorophyll concentrated in the darker green top part of their leaf. They also have a thick, rounded leaf-stalk which makes a more sturdy and stable base for the leaf, which helps keep it facing the sun when the breeze blows mildly so they can photosynthesize, but when the gusts get stronger, even these thick stalks can’t hold the leaves in place. Aspens, on the other hand, have adopted a completely different strategy for dealing with the wind! Their leaves a smaller, rounded, lightweight and papery, with a thin flattened leaf-stalk which allows them to flip back and forth in even the slightest of breezes. They also are able to photosynthesize better on both sides of their leaves, so when they flip flop in the wind, the tree is able to soak up more of the suns rays. This flip flopping gives them a shaky or shimmering appearance from afar, and that’s why they get their common name of either a Quaking or Trembling Aspen. Pretty dang neat to see how these two trees, while very similar, have each adapted in different ways to handle the wind that allows them to live in various niches! Like this vid?
