Colorado Blue Spruce
Picea pungens · a blue spruce
Planted for its stiff, silvery-blue needles and formal, pyramidal shape, a classic specimen or screen, and it grows more drought tolerant with age than other spruces. It needs cool summers and struggles in heat and humidity. Keep young trees watered, and give it sun and room for air to move.

Spacing

Place a row in your own yard and VeraScape spaces them at their mature width, so you can see whether they’ll crowd the walk.
