I've just noticed this which has grown up from nowhere over the summer in a neglected border and is now a good 60cm tall. It looks like a fig but I can't think how it could have got there, it's growing in the shady side of the garden, and I'm wondering if it's worth nurturing or not.
Any advice?
I do have one in a pot, which is much slower growing (understatement) and has much deeper indented lobes on its leaves so I don't think that could be the source, if the volunteer is a fig at all
