Included in Aster sagittifolius in Michigan Flora.
A plant of sandy oak savannas, open areas in oak forests, and also along sandy roadsides and powerlines. Either rare or overlooked; all but the Barry Co. specimens are old. This species resembles large individuals of S. urophyllum, with similar ascending panicle branches forming a relatively narrowly pyramidal inflorescence, but with longer bright blue rays of the same color as in S. oolentangiense. Plants are often somewhat more pubescent on the upper stem than S. urophyllum, which is glabrate.
