GENUS INDEX

GENUS CODE: SOLID
GENUS SCIENTIFIC: Solidago
GENUS AUTHORITY: L.
GENUS COMMON: Goldenrod
GENUS SUMMARY: A genus of 90-110 species, herbs, primarily North American, but with a few species in South America, Macaronesia, and Eurasia. The placement of the flat-topped goldenrods has been controversial; they are here included in Solidago rather than being treated as the separate genus Oligoneuron.
GENUS IDENTIFICATION: Identification notes: Several related genera readily mistaken for (and/or sometimes included in) Solidago are included here as keying “failsafes”.

HORTICULTURAL
Plant Sale Text: This is the only goldenrod in Eastern North America with white flowers! This relatively short and upright perennial can be found growing in dry, thin woods throughout North Carolina. This is a drought tolerant plant. Also known as Belly-ache-weed, Native Americans were quick to use this plant if any pain seized their limbs or body. It is a unique addition to the fall garden, and combines well with asters and other late-blooming perennials.
