Prairie Fleabane (Erigeron strigosus) vs. Philadelphia Fleabane (Erigeron philadelphicus)

Updated May 28th, 2023

These two species are usually easy to tell apart whether or not flowers are present, as they have major differences in flower structure as well as leaf shape and stem pubescence. E. philadelphicus prefers moister habitats, whereas E. strigosus prefers drier habitats with less competing vegetation, but ranges farther in all directions.

Philadelphia Fleabane (Erigeron philadelphicus) vs. Robin's Plantain (Erigeron pulchellus)

Updated May 16th, 2023

These two species can be confused, as both have abundant basal leaves and clasping leaves along the stem, both can be found in lightly-shaded habitats, and they have overlapping bloom times. They are easily distinguished by flowers, and they also have little overlap in habitat, although differences in habitat may require close observation. E. philadelphicus has a broader range, is more common and widespread, and is found in a wider range of habitats, preferring moister, more disturbed habitats with richer soils, tolerating poor drainage, and ranging into full sun. E. pulchellus is more restricted to drier, less-disturbed, lightly-shaded habitats, in soil of low fertility.

Philadelphia Fleabane (Erigeron philadelphicus) vs. Oakleaf Fleabane (Erigeron quercifolius)

Updated May 11th, 2023

These two species can be confused in their relatively narrow range of overlap. Both are found on moist sites, both tend to have a dense rosette of basal leaves of roughly similar size, and both have narrower, more numerous rays than other fleabanes. Because many of the characteristics used to distinguish these species have significant variation from plant to plant, and overlap between the two species, it is important to look at multiple features before making an ID. E. philadelphicus ranges much farther north and west, and prefers richer, finer-textured soils, whereas E. quercifolius is restricted to the southeastern coastal plain, ranges farther southeast, through all of peninsular Florida, and prefers sandy soils.
