is an attractive species, producing bright, symmetric flowerheads consisting of 8 to 24 (usually at least 12) pure white ray florets around a center of 12 to 24 yellow disc florets, borne at the ends of straggly, branched stalks that, like the narrow leaves (especially their edges), are covered by short bristly hairs. The hairy green phyllaries taper to a sharp, reddish-purple tip. The ends of the rays tend to bend downwards late in the day, straightening once the sun returns in the morning. The rays become pink when withered. Leaves grow at the base and along the stem, but the former are mostly withered by the time flowering occurs. They tend to be partially folded inwards along their axis.
The species is widespread in the US, and quite variable in terms of size, number of florets, and amount of hairiness.
