One of the unique things about the Hummingbird Exhibit at Philadelphia Zoo was that the way the exhibit was planted. It had a wonderful collection of plants and they were plants that were obviously all tropical but the selection of plants seemed to fit the ambience much better than at least what I had seen before, what had been done before. You can go into a, what they call, “A Tropical Exhibit,” and you see a Palm tree or you’ll see a calliandra or you’ll just see the typical, run-of-the-mill, usual suspects in terms of tropical plants. We had tropical plants in there that you didn’t see another institutes. You’d probably see ’em in botanical gardens because that’s where a lot of the stuff came from but it was totally different. It really gave you a feeling you were in some place special. Now, Chuck Rogers was the Head of the Horticulture Department at that zoo at the time. He was a great teacher and in that publication, although basically I wrote it, he’s the first author listed because he had the knowledge and he was able to guide me through everything basically was said in there.
