Colorado Spruce
épinette du Colorado
Picea pungens
This popular western US spruce is planted widely throughout North America for its colour and symmetrical layered form. The dense canopy is thick with stiff and prickly needles. The needle colour ranges from dark green to the silver blue that has identified the species as ‘Blue spruce’ (although some varieties are bluer than others). As the trees mature, the older foliage darkens while the tips of new growth are a contrasting glaucous blue. It can grow as high as 50 metres in the US west but will likely stop at half that height in this site and climate. When grown in the open, Colorado spruce keeps its branches all the way down to the ground. This tree is located in the Arboretum circle, about 6 metres west of the Fraser Fir.
