I too love how you can can shop by colors, I am seriously thinking of doing a section in the garden in a color like red after seeing a photo of a bed with that color, picture below. (not my photo)
I already have two iris that would fit the theme, Rip City and Red Handed, just clicking on their red list, I would have such a hard time deciding! Maybe I should do orange instead. No wait, maybe red-violet....ahhh too many choices!
Ohhhh, and a great list of rebloomers too!!
