Black Hills spruce (Picea glauca var. densata) is a small to medium-sized evergreen tree that is native to the Black Hills region of South Dakota.
It is a slow-growing tree that typically reaches heights of 10-20 meters (33-66 feet) and has a conical shape with a narrow crown. The bark is thin, scaly, and grayish-brown in color.
The needles of Black Hills spruce are short, stiff, and bluish-green in color. They are typically about 1 cm (0.4 inches) in length and are arranged spirally around the twig.
The cones of Black Hills spruce are small, cylindrical, and usually hang downward from the branches. They are typically 3-6 cm (1.2-2.4 inches) long and are reddish-brown in color when mature.
Black Hills spruce is well adapted to cold climates and can tolerate a wide range of soil types, including those that are dry, sandy, or rocky. It is often used in landscaping and as a windbreak or privacy screen due to its dense foliage and narrow crown.
The wood of Black Hills spruce is soft and light in weight, and is primarily used for pulpwood and lumber. The tree also has cultural and spiritual significance to the Lakota people, who consider it a sacred tree and use it in traditional ceremonies.
