Blue Spruce Plants

Tree Forms

• Stay patient with Moerheim, a tree form of blue spruce that matures to 30 feet high. Moerheim has dense branches, and this tree requires some time as it develops from its irregular appearance into an upright tree. Moerheim retains good blue color, according to the University of Connecticut Plant Database. Baby Blue Eyes, growing to 30 feet high and 15 feet wide, is a smaller tree cultivar of blue spruce appropriate for a small landscape. It possesses silver-blue needles and it grows slowly, at the rate of 2 to 3 inches per year.

Dwarf Tree Forms

• Mission Blue is a dwarf tree type of blue spruce. It grows quickly to between 10 and 15 feet. Mission Blue has blue-white needles, and like the majority of blue spruce plants, it is suitable for U.S. Department of Agriculture plant hardiness zones 3 through 7. After 10 years, Fat Albert should be 10 feet high on its way to about 15 feet tall. Fat Albert, named for the famous character from the Bill Cosby skits of the 1960s, is dense and broad, making it perfect for group plantings or to plant close to foundations.

Medium-Sized Shrub Forms

• Walnut Glen is a shrubby type of blue spruce that gains 12 inches each year until it reaches between 5 and 6 feet high. Some grow even taller, but this form works well as a foundation plant or a divider for property borders. Walnut Glen has powder blue needles, and it is compact, displaying a pyramidal appearance. Corbet takes longer to reach its full height, which is around 8 feet. In its first 10 years, Corbet grows about 36 inches, before achieving full height later on. Corbet has silver-blue needles, but its new growth is bluish-green.

Rounded Shrub Forms

• Globe is an option as a foundation plant or for rock gardens. It takes on a rounded, compact look, growing to 4 feet high and just as wide. Globe has greenish needles. Glauca Globosa has bluish needles; it grows 3 to 5 feet high and spreads out 4 to 6 feet. Glauca Globosa has more cold hardiness than the majority of blue spruce plants, growing into potentially frigid USDA zone 2. Its form makes it possible to plant multiple individuals in a row to create a hedge.
