Wyoming State Tree
Cottonwood
‘Salicaceae Populus deltoides’
The Cottonwood is a large tree with a clear bole and has an open spreading crown which gives the Cottonwood a somewhat vase-shaped form.The bark is gray to yellow-green and very smooth when young. As it matures the bark turns gray with thick ridges and deep furrows. The tree bears cottony seeds, about 1/4 inch long borne in a dehiscent capsule. The veined leaves are simple, about 3 to 6 inches long and are somewhat triangular in shape. The Cottonwood is the state tree for Wyoming, Nebraska and Kansas. Wyoming celebrates Arbor day the last Monday in April.
