Polygonum perfoliatum

Submitted by LoisStack on Mon, 07/26/2010 - 17:21.

I agree that the plant you described is not Polygonum perfoliatum. In addition to the characteristics you've listed as evidence, the leaf shape of the plant you found is not triangular, as you would expect with P. perfoliatum. Good job!
