This tree is a variety of the spruce species called Picea glauca, that is otherwise known as white spruce. While Black Hills spruce is said to be a variety of the white spruce, such classification is a much-debated topic, as some experts refuse to accept the same. The Black Hills spruce is scientifically termed Picea Glauca Var. densata/Picea Glauca densata. These trees are native to the Black hills of South Dakota, where they are found abundantly, that too at elevations of more than 6000 feet.
As compared to the original species, i.e., white spruce (Picea glauca), the Black Hills spruce is slow-growing and smaller. The latter has a darker foliage, which is found to be denser than the white spruce. The leaves or needles are greener in Black Hills spruce, and the cones are smaller. These trees are mostly conical in shape. The branches are compact and stout, with an ascending form of growth. Its bark is brownish or ash in color, and is flaky in nature. These trees are adapted to extreme cold temperatures.
