There's some great palm-bush-type plants at 3D Cafe in the free models area. I think they're in DXF. They import quite well. They'd look good in this environment. :) I also like the idea of using the Clivia stacked on top of itself twice or three times. The Clivia always strikes me as sort of alien and prehistoric. Or maybe just plain weird! :D
