I've thought about using some old wash tubs and a watering can that are from the 1940's - 50's for container gardens, but I can't bring myself to punch drainholes in them. We have such a mosquito problem, I don't want to have any standing water.

Last year I put a yellow Japanese iris and charophyte algae (sometimes called stonewort algae) in the bird bath. I also put tadpoles and snails in it. They eventually turned in to tiny toads (the tadpoles, not the snails). I haven't been to the local quarry to find more algae and tadpoles, but maybe sometime this month...
