100 Seeds Willow Aster Symphyotrichum praealtum Native Perennial Wildflower

Willow Aster (Symphyotrichum praealtum) is a native herbaceous perennial known for its slender, willow-like foliage and late-season display of small, pale lavender to white daisy-like flowers. This robust wildflower brings delicate texture and autumn color to meadows, pollinator gardens, and naturalized landscapes.
Ideal for borders, rain gardens, and prairie plantings, Willow Aster offers late-season bloom when many other flowers have finished. Its nectar-rich flowers are a valuable late-season resource for bees and butterflies. Plants may spread by rhizomes to form colonies in favorable conditions. Grow in full sun to partial shade in average to moist, well-drained soil.
