Weed ID

So to add to my potential list of Japanese knotweed, ground elder, mares tail and bindweed.

I think I have a new one, I have searched and searched weed sites, so it may not be a weed. They are growing in clumps, upright and at first I thought they were a primrose, but never flowered yet and got too big. The leaves have a similar texture, not green shiny but broad and growing off stems, still onyl about 30cm tall.

I know I need photos, but any way of distinguishing what typ of plants I could be looking at? There are now quite a few of them and this is untouched field that was plouged 2 years ago...I have a bank of weed seeds, some thistles are growing absolutely huge

 

It looks like comfrey plants, the same kind of leaves and colours, and compact growing of that size leaf, but I never planted it and so really doubt it is, but it is the only one I seen, I saw russian comfrey as a weed

 

Talking to myself here but Im betting it is foxgloves, again I have never seen any near me as nobody has gardens but I bet they will sprout those stems sometime soon and ta dah. Too the spade I go, they are remarkably resistant as I dug one out with a little soil left in the baking sun weve had here and it is still going
