Comments 6

This is a pretty, but ubiquitous plant that will appear on its own without any official encouragement. It can be distinguished from asters with similar flowers by its earlier blooming season and more numerous ray florets. Annual Fleabane differs from Erigeron strigosus (Daisy Fleabane) by its more numerous and broader leaves, and the long spreading white hairs that occur along the entire length of its stems. Daisy Fleabane, on the other hand, has more slender leaves and short appressed hairs that occur along the middle and upper portions of the stems. A similar species, Erigeron philadelphicus (Marsh Fleabane), has leaves that clasp the stems and its flowerheads have more ray and disk florets than Annual Fleabane. Return
