i wouldn't risk it....driftwood and rocks can be properly prepared, but any such measures that would have to be taken for live plants stands a good chance of killing them.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger-all down here on Earth.
