The specific epithet "annuus" denotes the plant's annual growth habit, though it can also behave as a biennial under certain conditions. The common name "fleabane" historically comes from the belief that the plant could repel fleas.
Morphological Characteristics Stem and Leaves:Erigeron annuus typically grows to a height of 30 to 120 cm. The stems are erect, often branched, and covered with fine hairs. The leaves are alternately arranged, with lower leaves being larger and petiolate, and upper leaves smaller, sessile, and clasping the stem.
Flowers:The plant is renowned for its daisy-like flowers, which are about 1 to 2 cm in diameter. Each flower head comprises numerous white or pale pink ray florets surrounding a central cluster of yellow disc florets. The blooming period extends from late spring to early autumn, attracting a variety of pollinators.
Seeds:Erigeron annuus produces small, lightweight achenes, each topped with a pappus of fine bristles, aiding in wind dispersal. This prolific seed production contributes to its widespread distribution.
