Showy Fleabane (Erigeron speciosus) is an extremely showy flower, producing masses of lavender, pink, or white flowers all summer long. But don't let its name fool you! There's no evidence that this flower repels flies or any other insects. In fact, pollinators love it! This plant is a vigorous grower that forms colonies over time and looks great in many different planting styles, including traditional mixed flower beds, cottage gardens, pollinator gardens, or natural meadow or prairie plantings. Deadhead to encourage more blooms if desired. *This plant is mildly toxic to dogs, cats, and horses.
