This specific cultivar of the Colorado blue spruce is known for its dense, symmetrical, and broadly pyramidal growth habit. Its silvery-blue needles retain their color well throughout the year, making it a desirable ornamental tree for landscapes. It is a popular choice for Christmas trees due to its strong branches and classic conical shape. A mature specimen can reach heights of 50-60 feet and a spread of 20-30 feet.
The hardiness and striking aesthetics of this evergreen make it a valuable addition to urban and suburban environments. It serves as an excellent windbreak, privacy screen, and focal point in landscaping design. Historically, the Colorado blue spruce itself, Picea pungens, is native to the Rocky Mountains and has been used for timber and various traditional purposes by Indigenous peoples. Cultivars like the Montgomery variety have been developed to enhance specific traits, such as denser foliage and improved color retention, making them well-suited for ornamental use.
