Summary

Populus angustifolia, commonly known as Narrowleaf Cottonwood, is a deciduous tree native to riparian zones, stream banks, and wetlands in the Western United States to Mexico. It typically grows to a height of 50-60 feet (15-18 meters) and a width of 35-45 feet (11-14 meters). The tree has a slender profile and often grows in groves where its roots can access abundant water. Its leaves are a distinctive yellow-green, lanceolate with finely serrated edges, fluttering in the breeze and turning yellow in the fall. The Narrowleaf Cottonwood blooms with catkins in early spring before leafing out, and its fruiting capsules release fluffy, cotton-like seeds that can blanket the ground. The bark is smooth and gray when young, becoming deeply furrowed with age.

This species is valued for its ability to stabilize stream banks and its fast growth rate, making it useful for quick shade and windbreaks. It is also planted for habitat restoration projects. In residential settings, it is less commonly used due to its large size and extensive root system, which can interfere with underground utilities. Narrowleaf Cottonwood requires ample water and thrives in moist, well-drained soils, preferring full sun. It is not drought-tolerant and may suffer from leaf scorch in dry conditions. While it has few serious pest or disease problems, it can be susceptible to cankers and wood rot. The sticky buds have historical significance as they were used by Native American tribes as a natural chewing substance.CC BY-SA 4.0
