A native wildflower with slender leaves and small white to pale purple daisy-like flowers clustered in panicles. An excellent late-season bloomer that attracts pollinators and thrives in dry conditions.

Why grow it

Panicled aster blooms later in the season than many native wildflowers, extending pollinator forage into fall when other nectar sources have declined. It tolerates drier soils and poor fertility better than many garden asters, making it useful for marginal areas where establishment is difficult. The species' narrow leaves and open branching habit offer a lighter, more naturalistic aesthetic than showy cultivated asters.

Watch out for

In wetter climates or poorly drained soils, the plant is prone to powdery mildew and other fungal issues, so ensure adequate air circulation. Dense planting or overhead watering can exacerbate disease pressure. The plant self-seeds readily in suitable conditions, which may require management if you want to contain it to a specific area.
