Fast-growing native cottonwood. Branches tend to be more erect than the Plains cottonwood. Narrow, willow-like leaves are shiny green in summer, turning golden yellow in fall. The hardiest cottonwood; can survive above 8000′ elevation. Prefers well-drained soils. Suitable for sandy, loamy, and heavy soils but does not do well in heavy clay soils. Wide-spreading roots can be useful in landscaping to reduce erosion and slow run-off water.

Throughout this site, the following are used as guidelines for watering established plants:
These truly xeric plants can live with our 12 inches of natural annual precipitation and only need a winter watering during a multi-year drought, but they will thrive with a monthly watering. Overwatering will kill some of these. These plants are adapted to intermittent deep
watering with soil drying to a depth of a few inches between waterings. Watering frequency may be every couple of weeks during the active growing season and maybe only one winter watering for optimal care. These plants need regular watering somewhat like a bluegrass lawn so that
they never dry to depth in the root system during the active growing season, and need occasional winter watering to prevent root dessication and resultant plant
death. About sizes of our plants:
Sizes indicated with a # are roughly the equivalent in gallonage; so a #2 is about a 2 gallon pot size; b&b stands for balled and burlapped.
