I love these large fragrant flowers that bloom twice for me every year. I did have 2 small groups that did not bloom this year, but I think that might be from my taking babies from them too much. Not sure. Otherwise, tons of flowers twice a year.

This was worth waiting for !
I love the soft lilac buds sheathed in spathes and the promise of pure white flowers.
It has produced breathtakingly beautiful blooms on strong stems, which have not been weakened by heavy rain and winds. This is one of the worst English summers that I've experienced.
I'm hoping for an increase in the rhizomes so I can take some over to my mother's garden .

I love love Immortality Iris, I bought it in Ebay, I know some sellers may have mislabelled the plant they sell but I really dont mind as I am bound to forget all these names just like all the plants I bought. "From our yard and too over grown. I am selling what I have cleared. We are not experts cutting these roots but my kids wants extra money, they will box it and send you extras. I researched this and believe its **Immortality**. You wont be dissappointed if you like iris all the time. Buy more and save on large flat rate box shipping"...that was his winning ad. I almost wished I didnt bid beacause I **do not like white flowers**, but I did because we needed a contrast to this yellow iris we have the blooms from spring until some heavy snows snaps the flower stems. When my husband opened the box, he said I just bought a lot of irises to get tired of. OMG, it was more than what we wanted to work on for that afternoon. The plants were so so fresh they seemed freshly dugged, dirt shooked, boxed and shipped. It is now 10/23/2012 I have blooms and flower stems on almost each root the ebayer sold me.What made me sign in to this site- is to let you know what the ebayer didnt mention, this is fragrant !!! I placed this beautiful glowing white iris in our foyer buffet, it filled the entrance with this delicate scent. Another plus that was not mentioned was the color is not flat white, its has a very light hint of lavender and stripes that make the flower seem to glow in our foyer, then the yellow beard!!! So pretty!!!! Thanks to the comments I read on this site, I found another iris of a different color that is truly delightful. Can anyone recommend a fragrant and reblooming TB iris that is not white or yellow as I have both already?

I grow Immortality in Vancouver WA zone 8. It increases well and doesnt have problems. Bloom is nice size. Not too big which is good for me. I think it rebloomed once for me in the past 7 years. It always puts on a great show in May.

Probably my favorite iris. It has rebloomed for me on even small new divisions. It is beautiful with roses and has a wonderful scent. If you are scared to pay the money for RB iris, this is the one to try. I have several pictures of it blooming on my blog. http://www.creativecountrymom.blogspot.com

This iris is a reliable rebloomer for me, and a robust grower. I love its small scale (by iris standards). It reblooms in early September. However, the fall blooms end up covered with Japanese beetles.

Had this plant before Linda gave me a piece and it died because it insisted on blooming in Oct not in the spring. I placed Linda's piece in a more sheltered spot and it bloomed in the spring and did not in Oct so it might live long enough to make babies. Lovely white flower and smells wonderful.

Fantasic grower with great increase. Mine's in a lot of shade and still sends up multiple scapes and reblooms. Earlier and shorter than the majority of Talls - first bloom is right after the border beardeds. Flower is not impressive in size or form - a grey/green white, but would do well in landscape situations in large clumps. Haven't gotten mine to set a pod and no success as a pollen parent yet either -hmm.

Grows quickly, have to divide every other year (but then I get to share the wealth with friends). Because of this I've only had it rebloom once for me in the past 5 years. Blooms early to mid-May in Nebraska (zone 5), before my other tall bearded iris.

I got a small tuber last fall, have a small plant this year but the bloom is huge! I'm looking forward to seeing it bloom again in the fall. Next year the plant will be larger.

Tall Bearded Iris 'Immortality' at 29" is a shorter Tall Bearded. It is a mid season bloomer and blooms again in the summer through fall. One of it's great points is that it reblooms pretty consistently across the US. It has been awarded The American Iris Society Honorable Mention '86; and the Award of Merit '90.
