Plant information:

"Doellingeria umbellata, known by the common names tall flat-topped white aster, parasol whitetop, or tall white-aster, is a North American plant species in the family Asteraceae. It is native to Canada (from Alberta to Newfoundland), St. Pierre and Miquelon, and the eastern and north-central United States (from Nebraska and the Dakotas east to Maine and South to Mississippi, Georgia and the Florida Panhandle.

Doellingeria umbellata is a perennial up to 200 cm (80 inches) tall, spreading by means of underground rhizomes. It can sometimes produce as many as 300 small flower heads, each with as many as 16 white ray florets and 50 yellow disc florets.

This perennial grows in full sun or part-shade and moist or draining wet soils that are best slightly acid in reaction, but adapts to moderately acid or slightly alkaline reaction."
