30 Seeds Persicaria punctata Smartweed Dotted Native Wildflower Pollinator Garden

Persicaria punctata, commonly called dotted smartweed, is a native herbaceous annual or short-lived perennial wildflower valued for its slender stems, lance-shaped green leaves, and delicate spikes of tiny white to greenish-pink flowers. Blooming from midsummer into fall, it brings an airy, naturalistic texture to meadow plantings, wildlife borders, and native plant collections.

Its late-season blooms draw bees, wasps, beneficial insects, and other pollinators, while the seeds provide food for waterfowl and small birds. Dotted smartweed thrives in moist to wet soils and is well suited to rain gardens, wetland edges, pond margins, bioswales, and other damp sites where many ornamentals struggle. It naturalizes readily in favorable conditions and pairs well with other moisture-loving native species.
