Smartweed
Persicaria pensylvanica
In the United States:
Native
· also called pennsylvania smartweed, pinkweed, smartweed
Honeybees forage on Pennsylvania smartweed for its abundant nectar, making it a valuable late-summer flow source that supports pre-winter colony strength. Peak bloom occurs from July to September in moist habitats. This native annual self-seeds aggressively in wet areas and may require management to prevent it from becoming weedy in gardens.
