3'-4' Blue Spruce
The species generally reaches a height of 65-115 feet at maturity with a diameter of 2-3 feet. It has a narrow, pyramidal shape and cone-shaped crown. As trees become older, they often take on a more irregular appearance. While blue spruce, known for the beautiful blue hue to its branching, grows relatively slowly, but is long-lived and may reach ages of 600-800 years.
