Plants for Phyllomedusa sauvagii setup?

[tjtreefrog]

I was wondering what the best plants for a Phyllomedusa sauvagii terrarium would be. I know my P. sauvagii like it dry (they are the only treefrogs I've seen run away from the misting bottle), so I'm sure succulents like Aloe vera and sedum would work. Does anyone know of a place online that sells organically grown succulents for terrariums?

Thanks,
Thomas
