Discussion
Variety lanceolatum is the northernmost variety, reaching the southern boreal region from Alberta to central Quebec and the island of Newfoundland. It is most variable morphologically and cytologically. The variety (and probably the others as well) is reported to hybridize with Symphyotrichum boreale, S. laeve, S. lateriflore, S. racemosum (documented by J. C. Semple and R. A. Brammall 1982), and S. puniceum (A. G. Jones 1989). Some of those hybrids need confirmation.
Symphyotrichum ×salignum (Willdenow) G. L. Nesom is of garden origin and is widely naturalized in central and northern Europe. It is the hybrid between S. lanceolatum var. lanceolatum and S. novi-belgii var. novi-belgii, and it may occur along the Atlantic seashore where the ranges of those two taxa overlap.
