Field Characters
Euthamias have bristle-like members on their pappus, rhizomes, and ray flowers that are greatly reduced.
Cultural Information
Propagation by seed is best and fresh seed germinates easily. Steffen (1979) recommends cold/moist stratification, possiably due to dormancy induced by long term storage. Seeds may be hand collected in lat fall (November-December).
Natural History
All of the goldenrods were called "verge d'or" by the Acadians of south Louisiana (Holmes 1990).
Habitat
Drying sites, especially in sandy or rocky soils and along roadsides.
