Description
The Eastern Cottonwood is a massive, fast-growing deciduous tree known for its open, spreading crown and deeply furrowed grayish-white bark. It produces catkins in early spring followed by capsules that release cottony seeds. The foliage is lush and famously trembles in the wind due to its uniquely flattened leaf stalks.
Habitat
Found primarily along streams, rivers, floodplains, and damp lowlands. Requires abundant moisture and full sun exposure to thrive.
Native Range
Native to eastern, central, and southwestern North America, extending from southern Canada down through the United States to northeastern Mexico
