Hi Coach B:
I don't know what it is, but someone else will. I dug out a bunch of grass yesterday that was growing in my sand (buffer zone) around my plants yesterday, and was it ever tough to get out, I don't know what it was, but it was purple at the very base of it. I think if I waited much longer it would have been really impossible. I planted some annual rye grass last year to hold the eroded/reclaimed sand in place while my plants got established, and that funky grass must have either (1) been in the seed mixture, or (2) been there all along, only smaller.
