Habitat:
Blue spruces grow as scattered trees or in small groups at middle
elevations of the Rocky Mountains on sites where there is a high moisture-level.
A deep root system anchors the tree against the wind. Although it prefers
deep, rich, moist soil, and full sun, it is hardy from zone 2 to 8, and
very adaptable and more drought-tolerant than most plants of this genus.
It is a slow-growing, long-lived species (up to 800 years).
Diseases: It is susceptible to fungal needle cast, fungal cankers, spruce bark beetle, spruce budworm and spruce gall aphid.
Distribution: This species is native to the Rocky Mountains from Colorado to Utah, New Mexico and Wyoming.
