Additional Info

There is a great deal of phenotypic variation within the genus Euthamia and morphological differences could be related to environmental factors. The "southern form" [syn. = E. tenuifolia var. microcephala (fewer florets per head and narrower, widely spreading leaves)] is easily recognizable and appears to be somewhat uncommon, being found in inner-dune swales, Coastal Plain seasonal ponds, power-line bogs and acidic fens in Sussex County and further south on the Delmarva. The typical E. caroliniana (syn. = E. tenuifolia) appears to be more of a generalist, occurring in moist swales and wet meadows.
