Daisy Fleabane resembles Erigeron annuus (Annual Fleabane), but robust specimens of these two species are fairly easy to distinguish. Daisy Fleabane is a more slender plant with fewer and skinnier leaves, and the hairs along the middle and upper portions of the central stem are short and appressed, rather than spreading outward. However, some malnourished specimens of Annual Fleabane can resemble Daisy Fleabane, thus becoming a source of possible confusion. While the fleabanes are often dismissed as 'weeds' because of their ubiquitousness during the summer, they are actually rather cheerful plants that are beneficial to many small insects that play an important role in the functioning of the ecological system.
