Brave of you to post a photo Keen. I think most of us are rather shy. The potty gardener and I have actually met. Some of us live a long way apart.
I have a huge single flowered rudbeckia, I think it's Herbstonne, which is a thug. My daughter once gave some Impatiens Balfouri as I thought it was pretty. It seeds itself everywhere and is related to Himalayan Balsam, not so thuggy as that though, and smaller.
