When thinking about evergreens in the West, you most likely picture the tall pines of Washington, Oregon and the redwoods or sequoias of California. These are majestic evergreen species. If you are looking for evergreens to fill your Western landscaping, consider different varieties of juniper (bushes and trees), mugo pine or blue spruce. Always check which plant zones in which a particular evergreen will grow best, making sure that it matches your location.
You won't get much shade with the skyrocket juniper, but it is suited for those locations that require a tall, fast-growing plant (1 foot or more per year) with a small spread. This juniper variety grows well in most Western states, zones 4 through 9. Be prepared for a mature height of 15 feet or more. The appealing dusty, bluish tinge to the foliage remains year round without fading or changing color. Because it is virtually maintenance free, needs no trimming, adapts to most soils and is drought resistant, it is an easy-care landscaping choice. It will do best in a full-sun location but can take a bit of shade, as well.
The mugo pine shows up in many landscapes of the West. It is a way of adding the crisp, dark green, needle foliage to a yard without having to deal with a similar tree that may grow upwards of 40 feet or more. The mugo is a small to large bush. The larger bush sizes can be trimmed to keep at a certain height or allowed to grow into the appearance of a small, bushy tree. The mops mugo pine grows to 3 feet in height and spread. The pumilio mugo pine will grow up to 10 feet at maturity. The mugo requires a full-sun location. However, it is drought resistant and needs little care. This evergreen is cold hardy to zone 2, making it a versatile temperature plant.
The blue spruce, sometimes referred to as the Colorado blue spruce, is native to the Rocky Mountain region. It is the state tree for Colorado and Utah. This evergreen also grows well in the West's southern-most states and is popular for landscaping, when the space is available. It can grow as tall as 50 to 75 feet at maturity, with a spread of 25 feet. When landscaping with this tree, make sure to leave enough room for it's mature state. It grows well in planting zones 2 through 8. Plant this popular ornamental tree in a full-sun location. It is not particular about the soil type. It produces 3-inch cones that can be fun to collect and use in craft projects.
