It grows here at my workplace in several "mega clumps"--the stalks are many, and they are full of flowers. Last year, the iris literally bloomed from February through almost to May.

'Celebration Song', TB, Schreiner, 1993: This iris has a spell-binding effect on me. Its colors are 'pastel perfect' with soft pink in the standards, and light lavender shades in the falls. Tangerine beards make it complete. Grows and blooms well, forming large clumps in 2-3 years. Dykes Metal winner in 2003.

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.
