Plant Labels

Fellow Hometalker Erica Glasener and I visited a new nursery together today and inevitably brought back a few plants. I bought a cardoon, which will grow into a large, spiky, distinctive plant. I'll put it by the street and I'm sure my neighbors will ask what it is.
My question is this: What are some interesting ideas for a label?
I'm not fond of plastic or wooden stakes.....so what have you used that worked well?
