Engelmann Spruce
Picea engelmannii
A tall, narrow, high-elevation spruce of the Rocky Mountains and interior West, forming dense subalpine forests with soft, blue-green, gently aromatic needles. Long-lived and slow-growing; its light, resonant wood is valued for instrument soundboards, and high-country stands are vulnerable to spruce beetle outbreaks.

Common questions
How do I tell Engelmann from Colorado blue spruce?
Engelmann spruce has softer, more flexible blue-green needles with a slightly skunky aroma when crushed and grows at higher elevations; blue spruce has stiffer, sharper, often more silvery needles. Their ranges overlap in the central Rockies.
What is Engelmann spruce wood used for?
Its light, even, resonant wood is a premium tonewood for the soundboards of guitars and pianos, alongside general lumber and pulp uses.
