Commonly Found Trees Adapted for Cheyenne
Crown spread indicates the spacing distance between tree trunks needed at planting, to allow for proper crown development at tree maturity. A diameter measurement of ground surface is indicated in feet for each species of tree to allow the minimum area for unrestricted root crown or trunk base development. Scientific names appear in italics (genus name and species name). If the second word of the scientific name is sp., that indicates there are more than one tree or shrub of that genus that can be recommended for planting in Cheyenne. The following includes the expected tree height and crown width at maturity. Other trees and shrubs rated for zone 4 or less may be available that are not on this list.
A street tree is usually located in the tree-lawn, which is the landscape strip between the street curb and sidewalk. Tree-lawn width varies from street to street. Tree-lawn width can be anywhere from 3 feet wide to 15 feet wide. Larger shade trees should be planted in a tree-lawn width of at least 8 feet. Cottonwoods, the largest shade tree in Cheyenne, should be planted in a tree-lawn of at least 10-12 feet wide, preferably 15-feet wide. A tree lawn width of less than 4 feet wide is usually not sufficient to support a tree without damage to sidewalk and curb.
