Trees and Shrubs for Cheyenne

A SHORT-LIST OF COMMONLY FOUND TREES ADAPTED FOR GROWTH IN CHEYENNE, WYOMING

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 (Ground diameter) 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.

EVERGREEN SHRUBS - CONIFERS:

Most are not suitable for planting on the public right-of-way.

Ground Surface Planting Diameter should equal the crown spread since the crown will obstruct or interfere with anything within the mature crown diameter. For example, a Juniper sp. 'Savin' will have a leaf crown radius of 5 to 6 feet and should be planted at least the same distance from a sidewalk, driveway, patio or building.

EVERGREEN-CONIFER SHRUBS SPACED 10 TO 12 FEET APART:

  • Juniper: Juniperus sp.
  • Andorra -
  • Bar Harbor - Height 1', crown spread 10'. Could plant on public right-of-way.
  • Hughes - Height 1', crown spread 12'. Could plant on public right-of-way.
  • Pathfinder -
  • Savin - Height 6', crown spread 10'
  • Scandia - Height 3', crown spread 12'.

Both ‘Bar Harbor' and ‘Hughes' will eventually grow over the sidewalk and over the street curb. Unsightly die-back can occur when this happens, due to mechanical damage.

BROADLEAF EVERGREEN SHRUBS:

Most are not suitable for planting on the public right-of-way.

Ground Surface Planting Diameter should equal the crown spread since the crown will obstruct or interfere with anything within the mature crown diameter. For example, a Yucca sp. will have a leaf crown radius of nearly 2 feet and should be planted at least the same distance from a sidewalk, driveway, patio or building.

EVERGREEN-BROADLEAF SHRUBS SPACED 3 TO 6 FEET APART:

  • Boxwood - Buxus sp. - Height 3', crown spread 4'.
  • Holly - Ilex sp. - Height 8', crown spread 6'.
  • Kinnikinick - Arctostaphylos uva-ursi - ground surface growing plant - Height 1', crown spread 15'. Kinnikinick can be used on the public right-of-way but it will spread over the sidewalk and street curb over time.
  • Yucca - Yucca sp. - Height 3', crown spread 3'
