Planting bedding plants in a concrete bird bath?

I have a concrete bird bath with a deep bowl and would like to make a victorian planter with it, my question is: Will the lime from the bird bath damage the plants? I'm planting a spike plant in the center and petunias in it for now, and some vines in the future when weather gets warmer.

Thanks, Connie

Zone 5 and it's still chilly.

sounds beautiful ! And yes the pea gravel sounds right,I am doing the same thing with an old plastic one that is split after our winter.I am zone 7.No need to worry about the lime it won't hurt the plants.
Reply:won't drainage be a problem? or will the concrete leech enough moisture, you think?
Reply:the concrete won't hurt the plants. just make sure to give them good drainage.
