Erigeron strigosus, commonly known as Prairie Fleabane, is an annual or biennial herb native to prairies, open woodlands, and meadows across eastern and central North America. It has also naturalized in parts of western North America, Europe, and China. This plant typically grows up to 31 inches tall and features hairy, petioled leaves. During its flowering season, which spans late spring to early summer, Prairie Fleabane produces numerous small flower heads. Each head has a central cluster of yellow disc florets encircled by white, pink, or blue ray florets, which are modestly showy and attract a variety of pollinators.

Prairie Fleabane is valued for its adaptability and ease of maintenance, making it suitable for wildflower gardens, meadows, and naturalized areas. It thrives in full sun to part shade and prefers well-drained soils, though it can tolerate a range of soil conditions. This species is drought-tolerant once established and can be used for erosion control. Gardeners should be cautious, as Erigeron strigosus can self-seed prolifically and become weedy or potentially invasive outside its native range. It is advisable to deadhead spent flowers to prevent unwanted spread.CC BY-SA 4.0
