| Habitat | In a variety of forest types and woodlands, often along trails, and in openings. More often found on roadsides, clearings, fields, and meadows. Occurs in a few calcareously influenced Longleaf Pine (Pinus palustris) savannas in Pender County. | |

| Identification | This species is rather like Annual Fleabane (E. annuus), but Philadelphia Fleabane has well-developed basal leaves at and beyond flowering time. Rays may be pink or white. The heads are wider than those of Oakleaf Fleabane (E. quercifolius), with rays 5-10 mm long (vs. 2.5-6 mm long). In addition, the basal leaves of this species tend to average wider and less shallowly lobed than in E. quercifolius. | |
