Siouxland poplar, a "cotton-less cottonwood" was introduced by South Dakota State University. It shares common traits with eastern cottonwood, but has slightly larger leaves. The main benefit of this extremely fast growing tree is that it does not produce the cotton that the eastern cottonwood does, making it a much less messy variety.
Populus deltoides "Siouxland" grows to around 80 feet tall and will succeed even in very poor soils. It has a beautiful pyramidal form with a rounded top, though it does require annual pruning to maintain this form. Pruning should occur in the winter, as warm weather pruning will leave this species vulnerable to pests and diseases. It prefers full sun, but will do just fine in partial shade as well.
