Castanospermum australe is a gorgeous tree. Deep green
pinnate leaves, and it is evergreen. I don't think it
would flower in pots indoors, so i think you should be
safe, as the seeds are toxic unless processed (even
then, the pods are huge - around 5 inches or so, and
the seeds are golf ball sized, and easily cleaned up).

I have a couple in pots indoors and they seem to be
doing fine. They are also very cheap. My three
seedlings were only about $16.00 USD for seedlings a
two feet high.

An interesting thing about the seeds though is that
they contain an alkaloid that appears to have anti-HIV
properties, preventing HIV from infecting cells.
