Can anyone identify this plant for me? It is growing in what used to be a raised hedgerow, but is now part of my garden. It comes up every year - and I consider it a weed. I pull up every stem I can see, but they come away clean from the underground base, no roots, and next year they appear again. I really would like a name for it - plus the common one if it has one!
Can I Roundup it, very carefully?.
