- Description
-
Medium to large, narrow, pyramidal conifer with horizontal branching to the ground. It is an evergreen gymnosperm tree that grows 30-60' and has a dense crown and is conic to columnar-conic. It is native to the central Rocky Mountains from southern Montana and eastern Idaho south to New Mexico. It does best in cooler climates, cannot tolerate heat and humidity.
It can be grown in average, well-drained soils in full sun, although it will tolerate some shade. This plant prefers rich, moist soil in full sunlight. Young plants should be kept consistently moist and not allowed to dry out. As the plant matures, it becomes more drought tolerant. This plant has a slow to medium growth rate. It is more drought-tolerant than other spruces. It is often utilized as a Christmas tree for its bluish color and stiff leaves for ornaments, but being replaced by Fraser fir due to dangerous pungent leaf tips that caused injury to toddlers. It is often planted outside afterward as a specimen plant.
Insects, Diseases, and Other Plant Problems: This plant has no serious pest issues but can be affected by aphids, scale, budworms, and bagworms. New growth and overall health of this tree can be affected by spider mites.
