Philadelphia Fleabane can be distinguished from other fleabanes (Erigeron spp.) by its clasping leaves and the greater number of ray florets on its flowerheads. Compared to Annual Fleabane (Erigeron annuus) and Daisy Fleabane (Erigeron strigosus), this plant prefers moister locations. In areas with mild winters, Philadelphia Fleabane may live longer than 2 years, although it is still short-lived. There is some variation in the characteristics of this plant across its range. These varieties are differentiated by the persistence of their basal leaves and the hairiness of their foliage. In Illinois, only the typical variety occurs. Another common of Erigeron philadelphicus is Marsh Fleabane. Return
