The Colorado spruce can be expected to grow in Hardiness Zones 2–7.
The Colorado spruce grows to a height of 50–75' and a spread of 10–20' at maturity. This tree grows at a slow to medium rate, with height increases of anywhere from less than 12" to 24" per year. Full sun is the ideal condition for this tree, meaning it should get at least six hours of direct, unfiltered sunlight each day. The Colorado spruce adapts well to many soils—growing in acidic, loamy, moist, rich, sandy, well-drained and clay soils. It requires normal moisture with moderate tolerance to flooding and drought.
Withstands wind better than most spruces due to a wide-spreading and moderately deep root system.
Is a long-lived specimen.
Features needles that are stiff, prickly and roughly 1–1½" in length.
Provides privacy and a windbreak when planted in a row.
Yields light brown, 3–4" cones which hang downward on the branches and are concentrated in the upper crown.
