100 Seeds Swamp Aster Symphyotrichum puniceum Native Perennial Wildflower

Swamp Aster is a robust native perennial known for its tall, upright habit and abundant late-season blooms. Its star-like flowers in shades of blue, purple, and lavender appear from late summer into autumn, attracting pollinators and adding vertical interest to wet or low-lying garden areas.

This species works well in rain gardens, naturalized plantings, and along pond or stream margins where its tolerance for moist soils is an asset. The blooms provide late-season color and pair nicely with other moisture-loving perennials and grasses in meadow or wildlife-friendly landscapes.
