    Is this plant Persicaria coccinea? Found it on the banks of the Charles River yesterday. Thanks! You can use it on the site if it is, I just wasn't sure.

    Answer

    Dear JulieMeyer, good morning. The answer is: possibly. The extremes of Persicaria amphibia and Persicaria coccinea aren't difficult to identify from photographs, but some individuals I would need to see the actual specimen or individual. The inflorescences and petioles do look too long for Persicaria amphibia, suggesting this is an aquatic form of Persicaria coccinea, but I would need to do measurements to be confident. I'm sorry if this isn't helpful.
