Inforescence:

Flowers: Daisy-like compound flowers (heads) at ends of branches; heads 1/2 in. wide, with 40-100 threadlike, white to pale pink ray florets encircling the yellow center composed of tiny, tubular disk florets; surrounding the saucer-shaped base of the head are several whorls of hairy, narrow, green bracts.
