Pineland daisy is a perennial wildflower native to moist flatwoods, bogs and freshwater marsh edges. Its attractive solitary flower begins as a purplish-pink bud that opens into a wheel of whitish-yellow disk florets and white ray florets (although a tinge of purple may be noticeable). Flowerheads are closed and nodding until midday, when they become erect and open. Leaves are elliptic and appear in basal rosettes. They have entire or slightly toothed margins, dark green uppers and densely tomentose undersides.  Stems are generally leafless, and are also tomentose. Seeds are born in achenes.

The genus Chaptalia is an homage to Jean-Antoine Chaptal (1756–1832), a French chemist, physician, agronomist, educator and philanthropist. The species epithet tomentosa and the common descriptor “woolly” refer to the tomentose leaves and stem. “Sunbonnets” alludes to the initial droop of the flowerhead, which resembles a bonnet.
