Which Picea pungens
We are planing to plant a picea pungens tree(blue spruce), but don't know which one to choose, as there are many different types.
The best one would be with very dense needles and a narrow growth and silvery blue needles. I don't like the ones that have completely blue needles(if there exists one like that). We had one that was 20 years old, but had to be cut down due to dissese.
What are your recommendations and experiences with blue spruces?
