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.

Editor's Note
Rhizomes (thickened roots) and rootstocks, fresh or dry, of all Iris species and cultivars are poisonous if ingested. Symptoms include nausea, vomiting, abdominal pain, diarrhea and elevated temperature following ingestion. Some resources claim the toxic principal (irisin, iridin, irisine) only cause low toxicity if eaten.
Skin irritation can develop upon contact with seeds, rhizomes, rootstock, or cell sap.
We tend to err on the side of caution in PlantFiles, and the danger notation in the details above is to warn gardeners, parents, and pet owners to look further for more information.

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.
