When I moved here in '97, a friend brought me several blue Iris. She's gone now, and so are the tags. I haven't been able to figure them out for years now.
The first one is a reliable re-bloomer in the fall. It's about 33' tall. My camera goes slightly blue.. It's a smidge toward to purple. Beard is blue at the tips.
The next one is shorter at around 26" and has a white beard. If it's the same one I have planted somewhere else in the garden, it's also a re-bloomer. Sorry that one picture is rotated
And finally, the one I call mottled Blue. Didn't measure this one, but over 30".. maybe 34"-ish
Your thoughts are appreciated.
