Annual fleabane flowers occur in clusters (panicles) in the upper parts of the plant, each 1/2-3/4" across. Disc florets are very small (2-3 mm) and golden yellow; the 50-120 ray florets appear very elongate (1/4-1/2") and narrow (~1-2 mm) and bright white in color. The back of the flower is covered with 2-4 rows of narrow, hairy bracts.

Philadelphia fleabane stems are usually unbranched except at the inflorescence, a panicle. Flowerheads are 1/2-3/4" across with 150-300 thin white ray florets, often pink or violet tipped, and densely packed around the 1/2" wide disc; the disc florets are yellow, tubular, and 5-10 mm long. The base of the flowerhead is coved by 1-3 series of light green, appressed phyllaries.

In Robin's plantain the basal leaves, stem leaves, stems, and flower stalks are all very hairy. Flowerheads arise from the tips of the stems as a group of 1-6. Individual flowerheads are 1-1.5" across; the numerous (50-100) ray florets bear long white (sometimes light pink or violet) petals surrounding a flat, yellow-orange disc of disc florets ~1/2" across. The base of the flower is surrounded with 2-3 layers of light green phyllaries (often with brown or purple tips) which taper smoothy into the stalk.

Daisy fleabane flowerheads are 1/2-3/4" across with 40-100 thin white or pink-tinged ray florets 4-7 mm long, usually shorter than the disc diameter and numerous yellow disc florets. The disc florets are tiny (1.5-2.5 mm), yellow, and tubular with five lobes on the apical end; there are five stamens and a single, bifurcated style. Around the base of the flowerhead are 2-4 rows of light green, 3 mm long phyllaries often covered with short hairs. Daisy fleabane is similar to Philadelphia fleabane (Erigeron philadelphicus), but the latter has larger flowers with more (150-300) ray florets and leaves that clasp the stems.
