Last Sunday I went to American Frog day 05' at the Atlanta Botanical Gardens and it was great!! TONS of dart frogs for sale. And, LOTS of vivarium plants. Black Jungle was there in its full glory, and I picked up tons of decorative junlge liana and 200 bucks worth of plants. They also had a vendor selling just vivarium-suitable orchids. It was great.

I posted a pic in the gallery of everything I bought. To make a long story short, I basically bought one of everything and I'm going to see what works best with my setup. I'll order multiples of the plants I like as time goes on.
