Colorado Blue Spruce is described in these nursery sources as a hardy ornamental spruce, not a fruit cultivar. Northwest Nursery says it is native to the Rocky Mountains and “absolutely hardy” in its North Dakota region. Daniels Nursery lists it among spruces for northern planters. [S1] [S2]
The sources give no breeder, release date, parentage, accession number, or cultivar origin. This is a common nursery name for a spruce sold in catalog trade. The sources emphasize hardiness, color, and landscape value, not fruit or food use. [S1] [S2]
Its main ornamental trait is foliage color. Northwest Nursery says the color ranges from dark green to shining silvery blue, with blue forms especially prized. Daniels describes Colorado Blue Spruce as brilliant blue-green, with intense steel-blue foliage, compact form, and symmetrical growth. [S1] [S2]
The tree was promoted for prairie and northern landscapes. Northwest Nursery says it had not known Colorado Blue Spruce to winter-kill or fail in drought. Daniels calls it a popular novelty for northern planters and valuable in landscape work. [S1] [S2]
These records document no edible fruit traits, culinary uses, storage behavior, disease observations, or breeding relationships. Its relevance here is as a named hardy perennial nursery entry from catalog sources. The packet does not support treating it as a fruiting cultivar. [S1] [S2]
