Very thorough answer, Mike.  I know what you mean as you describe the base
of the leaf color -- I saw some yesterday that had that deep wine color.

I've always associated it with health in the plant, and to know that it may
be natural fungicide or bactericide goes along with that..

The research project might be something that a high school student could do
??????  Or a whole class of comprised of young irisarians???

Anything written down that can be used for this?  Maybe we should talk
privately.  I think I've located just the teacher....
