Like Many, I Myself Love The Gorgeous Silvery Blue Of The Foliage. Blue Spruce Trees Really Catch The Eye & Will Stand Out In The Landscape. Being Extremely Cold Hardy & Able To Live In The Drastically Cold Temperatures Of Zone 1 As Well As The Warmth Of Zone 8’s Climate, They Can Thrive In A Large Variety Of Areas. They Are Popular As Specimen Trees In Homes, Parks, & Commercial Sites, & Being An Evergreen Conifer With Dense Branches, They Also Make An Excellent Windbreak. They Are A Superb Selection For Adding Color & Texture To Any Site You Choose For Them, & Their Unique Coloration Provides A Nice Contrasting Backdrop For Other Surrounding Standard Green Plants That May Otherwise Blend In To A Monochrome Landscape. Additionally, Blue Spruce Trees Can Help Prevent Soil Erosion.
