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.
