Blue spruce trees are an impressive species, so before you take to your property with a shovel and young blue spruce, there are a few things that you should know.
Here’s everything you need to know about the blue spruce tree!
1. The only place where the blue spruce tree is native to is the Rocky Mountains
2. Blue spruce trees can thrive in mostly any region
Although the tree is grown in high altitudes (from 1 – 2 miles above sea level), it can be found growing along stream sides and mountain valleys where the soil is a little richer in moisture.
3. Blue spruce trees are coniferous evergreens
They are proud members of the pine family!
4. On average, a blue spruce tree grows between 50 to 75 feet tall
Some have been known to grow outside of this range and when maturity is reached, their spread spans 10 to 20 feet across.
5. The lifespan of a blue spruce ranges from 150 to 600 years
The blue spruce is a slow-growing tree, living a long life unaffected by most elements. Its deep root system is strong and allows the species to remain upright, even in harsh winds.
6. A waxy layer gives them their blue hue
Blue spruce trees are noticeably blue-hued, because of the waxy, powdery layer that is found on the needles.
It is truly a unique characteristic that few other species have.

7. The blue spruce can lose its blue hue, too
Remembering that the blue comes from the waxy layer of the needles, it’s actually possible for a blue spruce to lose its color. It often happens when the tree is under attack by an outside infestation like cankers or pine weevils.
While you may be tempted to use a treatment to help your trees ward off this problem, it’s important to remember that some of these pesticides can cause the reverse effect, removing the blue wax coating itself instead of ridding the tree of the problematic pests.
Test any insecticide on a small portion of the tree before making any full application.
8. The blue spruce has a standard growth rate for a blue spruce is about 12 inches a year
Although they aren’t the quickest growing plants on earth, blue spruce trees grow at a pretty rapid and consistent pace.
However, in ideal growing conditions, the most expeditious spruces can gain more than 2 feet of growth in a single growing season!
9. This spruce tree shows incredible resilience
Once a blue spruce tree has gained its footing and has established a steady growth, there are very few things in nature that can hurt it.
– They can withstand droughts and air pollution
– Their spiky foliage prevents deer and rabbits from chowing down on branches
– Very hardy when it comes to fending off pests or diseases
– Adaptable in all sorts of conditions
10. The blue spruce tree is the official state tree of Colorado
On Arbor Day in 1892, school children in the state of Colorado voted to make the blue spruce the official state tree symbol.
It wasn’t until five decades later, in 1939, that the Colorado blue spruce was officially given this prestigious honor.
11. The blue spruce is also the official state tree of Utah!
Selected in 1933, the blue spruce earned the title of official state tree in Utah, found thriving across the state at various elevations.
