I agree with you Celia -- I like a variety too. It would be impossible for me to pick just one type of Iris as a favorite. It's much easier to pick what I DON'T like -- I don't care for Irises with speckles and splatters. Probably because I love the look of velvety-looking petals.
Edited to add: On the other hand, I love the new Irises that they're coming out with that have heavy veining on the falls!! Go figure.............
