The Black Hills spruce adopted by the South Dakota Legislature is considered a regional variety of white spruce (Picea glauca) found only in the Black Hills of South Dakota. This Black Hills distinction is not universally accepted however.

According to the S.D. Department of Agriculture, Division of Forestry:

Black Hills spruce is a variety, or subspecies, of the widely distributed white spruce. White spruce has bluish-green foliage while the Black Hills spruce has a typically denser and a bright bluish-green foliage. Black Hills spruce is also a slower growing species than white spruce. While Black Hills spruce has been given the variety distinction, it is now considered to be a geographical variety, rather than a botanical variety.

The Huronite and The Daily Plainsman reported that the Black hills spruce did not achieve official status without controversy. Proponents of the cottonwood put up a vigorous fight claiming that the cottonwood was more widely distributed throughout the state and had provided multiple benefit to early pioneers. They failed to sway the South Dakota Legislature in the end.
