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.
