Symphyotrichum laeve B. S. Walters

Aster laevis of Michigan Flora

Dry open forests (oak, aspen, jack pine) and thickets, especially at borders and clearings; fields and roadsides; sandy plains, bluffs, stabilized dunes; prairies, meadows, shores; rarely in wet places such as fens.

In its relatively few, large (long-rayed) heads this species somewhat resembles S. ciliolatum; furthermore, sometimes broad leaves below the middle of the stem taper to the base, even appearing to have narrowly to broadly winged petioles; however, S. ciliolatum does not have the clasping leaf bases so characteristic of S. laeve. The species is quite variable in leaf shape and number of heads. Also, some plants have long-creeping rhizomes, while others have only a short perennial base. The species might repay more detailed study.
