Weeds !

I am sure I'm cultivating weeds in the green house, I've even re-potted them! cant find them in any books that I've looked through, I'm sure one of you buding gardeners out there will email and let me know, but in the mean time I will carry on watering them until they flower, then maybe I will be able to tell what they are - The story goes, along the line that I was given a whole load of out of date seed packets from a friend who said "just see if anything comes up" ummmmm
I know they aren't stinging nettles, but they could be anything from Dahlias - lupins for all I know!!! they almost look like "Docks" except the leaves are softer and not wax-ish! ummmmmmm
