Re: Iris x norrisii

 Thanks for the information.  I am looking forward to "a ridiculous variety of colors, patterns, flower shapes, and number of blooms per stalk (think hundreds!) ".

There is a lot of potential variability for what conditions ×norrisii could grow in, because the parent species are quite different. Iris (Pardanthopsis) dichotoma is a northern species (Mongolia and Russia), while Iris domestica (Belamcanda chinensis) is southern (as far south as tropical SE Asia and the Philippines). Since (especially in the south) they can be grown to flowering from seed in one year, it would be easy to select seedlings for tolerating Florida winters. ×norrisii and dichotoma seeds require no cold dormancy. They *do* like summer heat just like beardeds, hence the difficulty in growing them well in the Pacific Northwest.

I would also hesitate to lump anything about the floral display of ×norrisii into one category. They have a ridiculous variety of colors, patterns, flower shapes, and number of blooms per stalk (think hundreds!), and of course bloom (here) in late July and August when no other irises are doing anything. The tall forms (~ 2+ meters) are open and airy, while the short forms (~0.3 m) put on a denser display of color. Very much worth figuring out how to grow well; certainly as much so as any bearded iris hybrid.
