It produces a single hairy, erect stem from a woody, branching caudex. The serrated leaves are up to 16 centimeters (6.4 inches) long and are borne on winged petioles. The inflorescence contains many bell-shaped flower heads. Each flower head contains 7-12 yellow ray florets surrounding 14-27 yellow disc florets.〔(''Solidago verna''. ) Flora of North America.〕 This species is the only goldenrod in the region that blooms in spring.〔 ''Solidago verna'' occurs in several types of habitat, including sandhills, pine barrens, and pocosins.〔 The three main habitat types are pocosin ecotones, the river terraces along the Little River, and wet pine flatwoods.〔 Threats to the species include the loss of habitat to development and agriculture, including silviculture. Fire suppression may degrade the habitat as well.〔〔Fleming, M. M. S., et al. (2007). (Effects and importance of soil wetness and neighbor vegetation on ''Solidago verna'' M. A. Curtis Ex Torrey & A.
