Colorado Blue Spruce
Blue Spruce cones
Douglas Fir cones
A sure way to tell a D Fir from a spruce is that there are no snake tongues (bracts) between the scales of a spruce and there are snake tongues (3 point bracts) between the scales of a Douglas Fir.
The needles of a spruce are sharp and rigid. The needles of both firs and Douglas firs are softer and not so pointed. It hurts to grab the needles on a spruce but not on firs and D firs…. Sticky Spruce… Friendly Firs
