Great show Jim, I evny you the visit to the Climatron.
There is a big hullabaloo going on right now between various factions in Botanical Gardens. One side wants labels on everything for educational purposes and the other side says labels distract from the overall look of the plant in the setting. I think many BG's are doing like the one you saw and IDing some plants but not all. Aquariums have graphics near the big tanks with pictures of the individual fish you might see, it is too bad BG's don't have something similar for the plants.
