I love the effect of these irises together — all different, but complementary. A little symphony of blues and purples. 
My only complaint is that I can’t figure out a way to cut some for the house with a reasonably long stem, since they’re sort of stacked on top of each other. I don’t want to denude the garden. I think I may just have to wait a few years until they’ve grown enough to have several stalks each, and then I can just cut a long stalk of each without leaving the iris garden looking bare.
In a few years, they’ll also be grown enough to need dividing (if you don’t divide them when the crowns start pushing out of the soil, they’ll start blooming less), so if you’re longing for irises and they aren’t in your budget, keep an eye out in July-ish for people dividing their irises who might have some to spare.
The speckled one is Iris Germanica “Batik” — I’m not sure of the other three — possibly including: “Best Bet,” “Sky Spirit,” “Blue Suede Shoes, “Cloud Ballet.”
