We are totally novice gardeners in need of help 
we have just uncovered a part of the garden from shingle and weed stopped fabric stuff. We've planted it up, but out of the ground is popping up this thick stalked furry plant. When the first one popped out I dug as deep as I could and accidently cut the stem weeded it out but now 3 more have appeared in a different part of the flower bed. previous owner was at one time an avid gardener so we are kinda used to odd things popping up 
Having accidentally weeded out poppies already need advice as to what this might be and to weed out or not to weed out??
