Geum radiatum is a rare species of flowering plant in the rose family known by the common names spreading avens, Appalachian avens, and cliff avens. It is native to the region of the border between Tennessee and North Carolina in the southeastern United States, where there are eleven known populations remaining.[4] The plant was federally listed as an endangered species in 1990.[4]
Geum radiatum is a perennial herb with a horizontal rhizome spreading beneath the soil. From the rhizome, several rosettes of leaves sprout. What may appear to be separate plants are actually all clones belonging to one genetic individual, as the plant reproduces vegetatively. The large leaves are decidedly kidney-shaped.[5] The stems grow 20 centimeters to half a meter (8-20 inches) tall and produces bright yellow flowers in the summer months.[4] This Geum looks very different from other species in its genus that grow in the area. Its closest relative is probably Geum peckii, which does not occur in the same region.[6]
Geum radiatum grows on a few tall mountaintops above 1310 meters (4367 feet) elevation in the southern
Fifteen known populations exist. Three others have been
