Fremont cottonwood (Populus fremontii) is a fast-growing native shade tree found in alluvial bottomlands and along streamsides at elevations from 0 to 6,500 feet. It thrives in moist soils with plenty of sunlight and is known for its striking, heart-shaped leaves that shimmer in the wind.
This tree is tough and easy to grow, reaching up to 100 feet tall and 35 feet wide when well-watered. It can grow 10–20 feet in a single year, making it ideal for large spaces but unsuitable for small gardens. Due to its invasive roots, it should not be planted near lawns or structures.
Often, only male trees are sold to avoid the “cotton” produced by female trees. Fremont cottonwood is ecologically important, providing habitat and food for birds and butterflies.
