Question
Hello. I found this plant in the Hellcat Area on Plum Island, MA. It looks like Canada Rockcress, and the distribution map indicates it's in the area. The green seed pods have a strong mustardlike taste; however, other plants looks quite similar, and I would like confirmation. Plum Island being a barrier island with a sandy substrate, the habitat didn't seem to match.
Answer
Dear chaffeemonell, your plant appears to be Turritis glabra (tower-mustard). This is a non-native mustard that is found here and there in New England in disturbed locations and clearings. Best wishes.
