Siouxland Cottonwood (Populus deltoides 'Siouxland') is a large, fast-growing deciduous tree that typically grows to a height of 50 to 60 feet and a spread of 30 to 40 feet at maturity. It has a broad, spreading canopy and a straight trunk with grayish-white bark that becomes deeply furrowed with age. The leaves of Siouxland Cottonwood are triangular in shape and have a glossy, dark green surface with a silvery-white underside. This tree produces small, round capsules that release cottony seeds in early summer, hence its name "cottonwood". Siouxland Cottonwood is a popular choice for landscaping, especially in wet areas such as near riverbanks or in floodplains, due to its ability to tolerate wet soil conditions and its rapid growth rate. Keep in mind that the growth rate and size may vary depending on the specific growing conditions and location.
