Bearded Iris 'Immortality'

‘Immortality’ is a tall-bearded iris introduced by Lloyd Zurbrigg in 1982. It has ruffled pure-white flowers with white beards and a sweet fragrance; published height records range from 29 to 32 inches. ## In the garden Use this German iris as a bright vertical accent in a sunny perennial border or cutting garden. Bearded irises prefer full sun and rich, well-drained soil, though they tolerate some shade. Plant the rhizomes at soil level or cover them lightly, and leave them unmulched. Once established, they tolerate dry conditions; heavy, wet soil can lead to rot. ## Flowering The American Iris Society profile describes ‘Immortality’ as a midseason bloomer and records summer and fall rebloom in Virginia. The 1982 introduction also reports repeat flowering there. These observations are climate-specific, not a guarantee of rebloom or a hardiness range. Height descriptions vary: the AIS profile gives 30 inches, its 1982 introduction gives 30–32 inches, and Schreiner’s 2016 catalog lists 29 inches. The profile notes pure-white ruffled flowers, white beards, and a slight sweet fragrance; Schreiner describes the fragrance as strong. See the [American Iris Society cultivar profile](https://wiki.irises.org/TbFthruJ/TbImmortality) and [Schreiner’s 2016 catalog](https://wiki.irises.org/pub/Hist/Info2016CatalogSchreiners/SIG-Catalog-2016-Collectors-LowRes.pdf). The [NC State Extension bearded iris guide](https://plants.ces.ncsu.edu/plants/iris-x-germanica/) gives broader group care and garden uses. ## Maintenance Remove faded flower stalks and divide crowded clumps in mid- to late summer after flowering. Clear old foliage at season’s end and promptly remove roots or leaves affected by iris borer.
