An erect, tall bearded iris which produces numerous flamingo pink flowers with flaring falls in late spring on stems up to 35’ arising from fleshy rhizomes. Green leaves are narrow (1.5’ wide), sword-shaped and up to 1.5” long. Drought tolerant once established. Dykes Medal award winner.
Subject to a number of pests and diseases. The most serious insect pest is iris borer which tunnels into the rhizomes and increases susceptibility to bacterial and fungal infections of the rhizomes such as bacterial soft rot. Various leaf spots can also be problems. Remove and discard infected rhizomes and plant parts. Aphids and thrips can cause damage to flowers and spread viral diseases. A regular, preventative insecticide spraying regimen may be the best way to keep tall bearded iris healthy.
