Glad to see that you are starting one. I think it needs a bit of refining though, for example, I was looking for a pure white, tall iris, and it brought up irises with any amount of white at all, and only one or two that I would call white. Some that I would call light blue, etc. You could have classes like selfcolor, plicata, amoena, etc. Very fragrant, somewhat fragrant, no fragrance.
