General Description

Each mid- to late spring, the tall stems of the Song of Norway bearded iris shows off white and palest blue flowers. 'Song of Norway' was a hybrid bred by Walter Luihn and released in the late 1970s. It received multiple awards, culminating with the American Dykes Medal in 1986, the highest accolade awarded by the British Iris Society for American-bred irises.

The distinctively shaped flowers of bearded iris appear on strong stems emerging from fans of light blue-green, sword-shaped foliage. The stems branch and carry numerous plump flower buds. Each blossom comprises three upright petals called “standards” and three drooping tepals (petal-like sepals), referred to as “falls.” On 'Song of Norway', the standards are ghostly very pale silvery blue while the falls are creamy white. Fuzzy bluebird-blue pads called “beards” are located at the base or shoulder of the falls, and give this popular garden perennial its common name. These blooms are pollinated by bees and make striking cut flowers, with each blossom lasting one to three days before shriveling up.

Bearded irises are tough, adaptable perennials which prosper in full sun to light shade and fertile, well-drained soils. Plant them with the tops of their slowly spreading, fleshy rhizomes exposed to the air. In hot summer climates, dappled shade in the afternoon is recommended. After three to five years, lift and divide the rhizomes and replant in late summer if the plants become too large or crowded. These rewarding, long-lived irises deserve a prominent spot in the mixed flower border or foundation bed. 'Song of Norway' will look stunning when juxtaposing darker blue or purple flowers on other perennials.
