Dotted smartweed is a wetland-adapted perennial that thrives in moist to wet soils along pond edges, stream banks, and rain gardens. It performs best in partial shade to full sun with consistently moist or even boggy conditions. Its small pink flower spikes attract pollinators and provide seed for waterfowl and songbirds in autumn.
