Taxonomy

Family: Asteraceae

 

There are three recognized varieties, two of which occur in the northeastern U.S. Relatively robust plants with ample and open inflorescences and long, divergent branches, and numerous and conspicuously reduced upper leaves are considered var. haleana Fernald. Less robust plants, with rather compact or narrow and elongate inflorescences and upper leaves more gradually reduced are considered var. nemoralis.

The other variety is more common in the Great Plains, and is called var. longipetiolata (Mack. & Bush) E.J. Palmer & Steyerm; it is a tetraploid and more robust than the other, diploid varieties. It may warrant species status, in which case it would be called S. decemflora DC.

Habitat

Old fields, remnants of dry prairies, lake dunes, sandy black oak savanna.

Associates

In old fields with Ambrosia artemisiifolia elatior, Aster pilosus, Fragaria virginiana, Hypericum perforatum, Monarda fistulosa, Potentilla simplex, Rudbeckia hirta.

 Distribution

Nova Scotia west to Alberta, south FL to TX.

Morphology

Short herbaceous perennial. Leaves gradually reduced in size from near the base of the plant into the inflorescence. Cauline leaves finely pubescent, somewhat scabrous, the blades of the lower ones more than 4.5 times as long as wide, usually long-tapered into the petiole, subentire or serrate-crenate with low teeth. Flowers yellow; heads in terminal panicles, secund along the upper side of the branches.

Notes

Flowers early August to early November

Wetland indicator: Upland

Sometimes called Gray Goldenrod because of the somewhat downy surface of the leaves.
