We moved in last September and I keep finding plants/ weeds in the rather neglected borders. This one started to come up as tiny leaves looking as it had self seeded randomly in cracks and corners. I potted some up but can't make my mind up what it might be. It looks a bit like Lupin, but there are no Lupins around and the seedlings were so small that it seems unlikely that a huge seed like Lupin's could produce a weakling like that. Also, the leaves are too thin. There's something like Potentilla there as well, but the leaves are too narrow and not very serrated. Anyways the foliage is nice so please can you identify it as a prestigious plant instead of a weed? The leaves are now about palm size. Thanks very much!
