The Eastern Cottonwood is both a fast growing and a short-lived tree. Trees have survived when as much as 3 feet of silt has been deposited, a new root system developing just under the new surface of the ground.34Growth of cottonwood trees depends upon the texture of the soil and its internal drainage. The leaves are dark green in the summer and turn yellow in the fall. Regnum Vegetabile 154. Favorable soil moisture must prevail, for seeds remain viable under dry conditions for but a few days.
