MY weed from H....!
I don't know the name of this weed - but I can describe it pretty well:
It grows from runners, medium colored green rosette, the size of a silver dollar...(sort of, not really, but sort of looks like a small coreopsis, but flatter). It's driving me NUTS! i can't get rid of the stuff because it is spreading by runners and tangles into everything.
I didn't have it the year before, last year I let it go because I thought it was a reseed but unfortunately, it wasn't and by that time, it had spread like crazy.
Thanks for any input
