Colorado Blue Spruce (Picea pungens) is a beautiful native American conifer. They are slow growing and a rustic silvery bluish green colour, accentuated by the sharply pointed foliage. It will live two years in the purchased pot size. After this they will need to be re-potted into a larger size pot. Watering 2-3 times a week, pruning and replanting must be in done in cooler months.
