It seems this plant is on the move as, according to Hemmerly, Dr. Robert Kral of Vanderbilt University noted in 1973 that it had only recently become common in the cedar glades in the Central Basin of Tennessee.

Snakeroot is the vernacular for the Gutierreza genus which this plant was once placed. The 'broom' in the name supposedly comes from the shape of the plant being somewhat like an upended broom.

One of the best general guides to wildflowers of the North Eastern and North Central United States. Newcomb's key is an excellent, simple method for identifying plants. Newcomb has drawings for almost every plant mentioned that are excellent aids to identifying the species. Though only the more common plants are covered this is often the first book I pick up when trying to identify a wildflower.
