Pennsylvania smartweed (Persicaria pensylvanica) is an adaptable native annual-to-perennial that thrives in moist to wet soils and partial shade. It produces small pink flower spikes that attract pollinators and its seeds are highly valued by waterfowl and songbirds. Minimal care is needed; simply provide consistent moisture and it will naturalize readily.
