Unique Features: The Siouxland Cottonwood is a male clone so there’s no cotton fluff to deal with.  The Siouxland Cottonwood is a selected and named variety of the Eastern Cottonwood.  It was selected for its smaller size, and especially its narrower width. Even so, this is not a tree for small yards.  Cottonwoods use a lot of water to maintain their rapid growth rate and to support this they have a very aggressive root system that can cause damage. Cottonwoods also have softer relatively weak wood and can drop large branches. With all fast-growing trees, proper and timely pruning will prevent potential problems and improve the health and longevity of the tree.  The right planting site is important in order to prevent problems.
