Last year I had a great plant on the front porch but never did find the name - this year I planted it again and the tags were in the little pot. It is: Silver Plectranthus - it grows about 24" long in a vine like manner so is great in large pots. The leaves are really unique, they are soft and fuzzy with depth to them. The picture I posted is from last year. I will take some this year but the plant doesn't show well enough yet.
On another note, I was surprised you are to store canna lilies bare rooted - I'll try that this year.
