Hello friendly botanists,

I am trying to get a better identification handle on the spruces.

When the cones are nice and well developed, I am fairly comfortable
to ID a white spruce (longest cone), and black spruces with their dark
violet colored cones are also recognizable. And the intermediate red spruce
cones are also ok(ish).

In the absence of cones, hairs on the young twigs are used to identify
the species (no hairs for white spruce).

I took some photos (linked below) with labels for black, red, and white
spruce (based on cones that were on the trees but not in the photos).

One spruce looked different.
I tentatively labelled it 'Norway Spruce', because it appeared to be
very fast growing (1 foot per year under canopy, some 10-15 year old),
had 'red spruce like needle color' (subjective), and no hairs on the branches.
It could also be a white spruce, even though its new growth and needle
attachment does not look like in the white spruce.

I welcome any comments or advice.

Burkhard
