The Colorado blue spruce (Picea pungens) grows too large – some are as tall as 120 feet – to be a practical landscaping tool for small and medium-sized yards. Luckily, for those that enjoy its bluish-green foliage, the Colorado blue spruce is available in dwarf form. While these handsome trees are able to stand alone as a specimen plant, their reduced stature enables you to use them in a number of other ways on your property, provided you live in a part of North America where this species can grow unhindered.
Choose to landscape with the dwarf types of Colorado blue spruce if you live in U.S. Department of Agriculture plant hardiness zones 3 through 7. Warmer zones are not suitable for these trees. Cultivars such as Corbet, Baby Blueyes and Colonial Gold are cold hardy to USDA zone 3, displaying the same tolerance in winter as the parent species does.
Locate your dwarf blue spruce trees in acidic soil that drains well and is of medium moisture. Keep the ground damp as the trees establish themselves during their first years. Place Colorado blue spruces in full sunshine; these dwarf forms do have some tolerance for light shade.
Group dwarf forms of the Colorado blue spruce together to create groves if you have a large enough area on your property. Cultivars such as Corbet are appropriate for this application. Corbet grows between 3 and 8 feet tall. Use Thume, another cultivar of similar size, in your mass plantings. Thume features powder-blue needles, notes the Missouri Botanical Garden.
Support the branches of Pendula, a weeping form of Colorado Blue Spruce, with stakes. The arching, drooping branches will grow downward when you give the main trunk enough support. Some landscapers opt to allow this cultivar to grow without support, resulting in a tree that sprawls along the ground, with branches up to 10 feet in length trailing on the surface.
Situate some of the larger types of dwarf blue spruce in rows to make a privacy screen on your property borders or in front of your house. Suitable forms for this task include Baby Blueyes and Colonial Gold. Both grow between 15 and 20 feet tall, featuring dense foliage that keeps anyone from seeing through.
