Thanks to everyone for the great ideas! I should have clarified - they won't be using THESE plants for research. Just to look at, more like a mini botanical garden. But I'm sure some of the more creative scientists that work there will be picking the peppers and other stuff we put in. Some of the plant material specified includes: cinamon, nutmeg, bananas, lemons, and ginger...hmm...Sounds like a good recipe for chile banana bread! Now I'm hungry... :-) Helen
