Black Hills SprucePicea glauca var. dens
The Black Hills spruce is the state tree of South Dakota, and for good reason. This variety of the more widespread white spruce is found naturally only in southwest South Dakota and a small portion of northeast Wyoming. In fact, it is the only spruce native to the Black Hills region.
While not as widely known as other spruces, one tree expert claims that it is “ornamentally superior to the standard white spruce” and can be planted just about anywhere that the more common Colorado spruce will grow.
