I grow a lot of things from packets of mixed seeds ,such as Chilterns 'lottery mix' in which could be anything. Well, this is a plant that I grew about 3 years ago, I planted it out last spring, and there it sat,I've not been able to identify it, until this morning. I've noticed that it's got flowers forming, and as soon as I saw them,I've got a notion that it's a hardy geranium....one of the tender sorts..could I be right?i know that the experts out there will know.
