Blue Ridge goldenrod, Solidago spithamaea, is an erect perennial herb, 4-8 in (10.2-20.3 cm) tall, arising from a short, stout rhizome. The stem is thickened and strongly ribbed at the base, and becomes tinged with red toward the end. Leaves are smooth, lance-or spatula-shaped, 3.2-6 in (8-15 cm) long. The plant produces yellow flower heads arranged in a flattened cluster, called a corymbiform inflorescence. The plant spreads vegetatively by extending shoots from its rhizome.
Blue Ridge goldenrod is one of a few southeastern representatives of a genus that is more widespread in northern alpine habitats. The name of the genus comes from the Latin words solidus and ago — to make firm—and refers to purported healing properties of the plant family.
Blue Ridge goldenrod grows in full sunlight in dry rock crevices of granite outcrops on the higher peaks of the Appalachian Mountains that experience perhaps the most extreme winter conditions in North Carolina and Tennessee. The shallow soils are highly acidic. The habitat elevation is above 4,000 ft (1219.2 m).
This plant is endemic to the higher Appalachian mountain peaks of North Carolina and eastern Tennessee.
Of the three known populations of Blue Ridge goldenrod, two are located on private land at Grandfather Mountain and at Hanging Rock in Avery County, North Carolina. The third population occurs within the Cherokee National Forest at Roan Mountain, straddling Mitchell County, North Carolina, and Carter County, Tennessee. The most vigorous stands of the plant, numbering several thousand stems, grow on Grandfather Mountain.
Blue Ridge goldenrod has been damaged by large-scale recreational development of at least three other open mountain summits where it formerly grew. Construction of observation platforms, trails, parking lots, access roads, and suspension bridges destroyed plants and opened previously inaccessible portions of habitat to hikers and sight-seers, who have severely disturbed plant sites. As one botanist put it, Blue Ridge goldenrod seems to have an instinct for growing in the most scenic sites, thus coming underfoot.
Conservation and Recovery
Hanging Rock is currently being developed into a ski and resort area, but the landowner has agreed to cooperate in the site's protection. Grandfather Mountain is also being developed as a commercial recreational site, but a conservation agreement has been in place there since 1983, ensuring cooperation of the landowner.
Additional development in the National Forest will not occur without proper consideration of effects on goldenrod populations. The Forest Service has crafted a management strategy to rid goldenrod sites of encroaching shrubs and will consider redirecting hiking trails away from plant populations. The U. S. Fish and Wildlife Service, the Forest Service, and the North Carolina Department of Agriculture have cooperated extensively to conserve the plant.
The Blue Ridge Goldenrod Recovery Plan sets the objective of attaining five self-sustaining, protected populations. This will require stabilizing and expanding the three existing populations and discovering or transplanting at least two more. At that point, the species could be considered for delisting.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
