Black Hills Spruce (Picea glauca var. densata) – The Black Hills spruce is the state tree of South Dakota, and for good reason. This variety of the more widespread white spruce is the only spruce native to the Black Hills region. The Black Hills spruce grows to a height of 30–60' and a spread of 15–25' at maturity. The Black hills spruce is not as drought tolerant as Blue Spruce and cannot tolerate flooding, it is however very adapted to cold and is very resistant to winter injury. Black hills spruce are used for lumber, pulpwood and Christmas trees as well as being good yard and ornamental trees.
