DistributionMountains; sparingly the northern Piedmont, disjunct to Warren County. However, there are records in the adjacent southeastern Piedmont of VA.

Newf. to MN, south to VA, northwestern SC, northern GA, northern AL, and TN.
AbundanceInfrequent to locally common in the Mountains; very rare in the northern Piedmont close to the VA border.
HabitatWet meadows, wet pastures, openings in floodplain forests, montane seepage bogs, fens, and marshes.
PhenologyFlowering and fruiting July-October.
IdentificationStems usually grow 4-7 (-8) feet tall, with many lance-ovate leaves that are 6-15 cm long (vs. 4-11 cm long in D. sericocarpoides). Note the different habitats and montane range. As with our other two Doellingeria species, rays are white and disks yellow (turning brown). A plant in bloom with its numerous and large white flowers and flat-topped (or dome-topped) inflorescence is quite striking.
Taxonomic CommentsOlder references named this as Aster umbellatus var. umbellatus.

Other Common Name(s)Parasol Flat-top, Flat-topped White Aster, and many others. The species formerly named as Aster umbellatus was generally named as "Flat-topped Aster". It is best to name the two tall Doellingeria species as "flat-top asters" and leave "white-top aster" to those now in the genus Sericocarpus.
