Field Characters

Euthamias have bristle-like members on their pappus, rhizomes, and ray flowers that are greatly reduced. Similar to E. leptocephyla which has leaves which are 2-5 mm wide, are 3-5 nerved and the tops are covered with glands giving the leaf a shiny appearance. Euthamia tenuifolia's leaves are 1-1.2 mm wide, 1 or 3 nerved and are dull on the upper surface.

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

Open sandy places.
