I must admit to you upfront that not only am I a black thumb, but I don't much care to name the five types of oak or sourgum or various other types of flora found ... everywhere. Finding rare types of weed don't do much for me, so, know that my review is rather biased without interest in the display. However, it was a lovely and dense exhibit of a plethora of plant species across the general types of biomes, I assume, are found around the world.
There was a tropical room and, unless we're counting Puerto Rico (which is totally a legit argument to be made), the U.S. has no tropical biome. The building is beautiful, full of glass, light and distinct smells to the flowers and other flora found in each biome, which included temperate, tropical, desert, Hawaii, and rare species exhibits.
The tropical was the largest and central room to the museum and had a second-floor walk to get a top-down view of the main room. Though a short trip for this admitted black thumb, it was thorough and definitely the kind of place someone who loves plants could get lost in. Also, there were more than a few people sitting and merely relaxing under the flora on a number of benches throughout the museums.
