Could this be Immortality?

It is tall, sturdy, fragrant, inside 3 doo-hickeys are all white, beard, white to near orange near the top.

Here is another view:

I have Immortality but a CLOSE Up really would help i.e.beard .Maybe you can take a picture from each side and also the top.

Immortality is 'supposed' to rebloom, give it extra water this summer and see if it does. If it does, then I would say it is that. If it doesn't, then it still could be that or be anything else!

Check plant files. I think I remember that the beard on Immortality is yellow.

check Diamond Bracelet.

Immortality has yellow beards and is not 'tall'......about 29-30 inch. One of my shorter Iris.

Hmmm....The one I have was supposed to be something else, but it is beautiful and enduring whatever it is!

my immortality stays short, not even 30 inches, more like 18

I guess that might depend on the soil ect.

It certainly doesn't have lots of frills.

best way to find out is to buy Immortality and compare at bloom time

Well, I canpretty much assume that it isn't immortality! Is there a source somewhere that lists irises by various attributes?

Here is my Immortality (close up). Mine is not real tall, may be 20 inches and it's not that big like yours. Yours are beautiful though. However, I do have a white iris that is pretty big and falls over w/o support. Let me see if I can find photo.

Here is my Lacy Snowflake. I don't know how anyone can tell the difference between all the whites. Thank goodness I labeled them.

I took a picture of the very center of my Immortality. Maybe this will help.

Note that Immortality has yellow beards.

Well, I suppose it doesn't really matter what it is, (It was SUPPOSED to be Octoberfest) but it is a real winner, whatever it is. It is up to my nose this year, very sturdy and well placed branches (I don't know how they count branches, but to my eyes there were 5 branches with double socketed blooms on my largest plant. It has a center like the photograph above, and the beards are light yellow to orange at the center. It has a pleasant fragrance, what more could I ask? Oh, it has survived the borer wars for 30+ years. It was one of the first irises I ever bought.
It now has a name:
"Gift of Angels noid"

Great.

well, just enjoy it. It sounds beautiful. May they multiply so you can share.... :)
