General Description:Picea pungens is one of the most popular and widely planted spruces in the Chicago area. It is a very adaptable tree well-known for its formal, dense, stiff habit and blue foliage. However, the foliage color can vary from green to slightly blue to strikingly blue. For consistent blue foliage a grafted named cultivar should be selected. Colorado spruce is native to the central and southern Rocky Mountains and once established, is considered one of the most drought tolerant spruces species.
