Common Fleabane

<em>Erigeron philadelphicus</em> is an annual or biennial herbaceous plant in the family Asteraceae, order Asterales, commonly known as Philadelphia fleabane or common fleabane. This species produces numerous small, pale pink to white daisy-like flowerheads with many narrow ray florets surrounding a yellow disc center. <em>Erigeron philadelphicus</em> has a broad distribution spanning Asia, Europe, and North America, where it is native and widely naturalized. It typically grows in moist, disturbed habitats such as meadows, roadsides, stream banks, and open woodland, tolerating a wide range of soil types and moisture conditions. The plant is generally considered a common weed in many parts of its range and is notable for its prolific seed production, which facilitates rapid colonization of disturbed ground. Despite its weedy tendencies, the species provides valuable nectar resources for pollinators. Biological traits of this species remain poorly documented in the scientific literature.
