Polygonum perfoliatum

Submitted by LoisStack on Mon, 07/26/2010 - 17:25.

I agree that you did not find Polygonum perfoliatum. Not all plants are so distinctive that you will "know them when you see them" ... but P. perfoliatum is very distinctive. I've looked at a lot of plants, but I have never seen a plant with such triangular leaves. So ... I think that with the observations skills you are developing, when you make another trip to look for this plant, you WILL know it when you see it!
