Utah juniper pdf

Utah juniper - Juniperus osteosperma (Cupressaceae family)

Habit: Upright evergreen that is more round than pyramidal in form as a mature tree. As a young tree it can have a single central leader, but as it matures it develops a short multi-stemmed appearance typically with low branches.

Hardiness: Zone 3 to 7

Leaves: Scale-like, short-pointed, usually opposite in four rows, and yellow green in color.

Twigs: Young twigs are covered with scale-like leaves for several years. Older twigs are reddish brown eventually becoming gray in color with time.

Bark: Gray, very fibrous and exfoliating

Flowers: Male and female flowers are usually on the same tree.

Fruit: Berry-like and ¼ -⅝ inch in diameter Fruit takes two years to mature and usually has one seed inside. Color is bluish-white when young, reddish brown as they mature.

Similar Tree Differences: Native to the Intermountain West the Utah juniper is often confused with the Rocky Mountain juniper because they are so similar. These two conifer tree species differ in the following ways: 1) The needles on Utah are yellow-green and Rocky Mountain has gray-green foliage; 2) On Utah the bark is gray and on Rocky Mountain the bark is reddish-brown; 3) Utah juniper usually has male and female flowers on the same tree, whereas on Rocky Mountain the male and female flowers are found on different trees.

Landscape Value: Utah juniper is drought and alkaline tolerant. Suited to dry rocky sites this tree is hard to find in the nursery trade, because it does not possess the striking foliage or form of the more typical landscape junipers. Landscapes that contain Utah juniper are often created using indigenous stands.

Diseases/Insects: No major pest problems observed on this tree.
