ITS NEVER FLOWERED JUST GROWS BIG LEAVES AND CAN IMATATE WHAT ITS GROWING AMOUNGST NO WEED KILLER WILL TOUCH IT AS ROOTS CAN GO DOWN TO 18 INCHES AND WILL SNAP OFF THIS WINTER I HAVE COVERED MY BEDS IN PLASTIC SHEETING BUT IT HAS STILL COME BACK
Weeds with deep roots can be killed with repeated applications of a weedkiller such as SBK applied to any new growth. Plants like this store energy in their roots to make new shoots so just covering with plastic or cardboard isn't going to do it.

Certainly looks like Coltsfoot but I've never known it to be a persistant problem. It flowers very early in the year before the leaves appear which make it an excellent source of nectar for early bees. Goldfinches, siskins and redpolls all love the seeds which are a good early food source for them. If you've got pet rabbits they love the leaves too and they dry well if you want to store them to add to their hay.
It isn't an especially vigourous grower so just keep weeding it out and it will go away without needing to resort to chemicals. Don't let it seed if you're trying to get rid of it. I've had it in my garden for years now and it's a welcome plant as the foliage is quite unusual and ornamental in my opinion.
