Question
Growing beside a driveway in Massachusetts. Thinking it looked like Persicaria I tried the key but got stuck at the choice between perennial with rhizomes or annual. I could pull one up to check but I'd like to try non-destructive identification first.
Answer
Dear jfc, I don't have quite enough information to go on from the images (despite the fact they are great images--thank you). You might have Persicaria extremiorientalis (far-eastern smartweed), which is recently found introduced in MA. If you want to collect a specimen and sent it my way, I can tell you with more certainty. My email is ahaines[at]nativeplanttrust.org
