What is a cottonless cottonwood tree?

Male cottonwood trees are referred to as "cottonless cottonwood trees" because they lack the feathery seeds that a female tree has. Cottonless cottonwood trees are also known as Populus deltoides.

These trees grow quickly, have dark green leaves and are hardy in USDA Hardiness Zones 3 through 9. Cottonless cottonwood trees grow 60 to 80 feet high and need a large amount of water to live. The foliage of cottonwoods becomes a vibrant yellow in the fall. These trees are susceptible to a host of pests, including mealy bugs and aphids, as well as diseases such as sooty mold growth.
