IRIS 'Immortality'

Image of Iris 'Immortality'

Jesse Saylor

Family

Iridaceae

Botanical Name

IRIS 'Immortality'

Plant Common Name

Bearded Iris, Immortality Bearded Iris

General Description

Pure white flowers are what distinguish 'Immortality.' This tall bearded iris has large, six-petaled blooms with three frilly white petals that curve upwards, called standards, and three that curve downwards, called falls. These are fragrant and have ivory beards at the base of each fall. Like all bearded iris, ‘Immortality’ has sword-shaped, medium green leaves that are equitant, or fan-like, which are born from slow-spreading bulbous rhizomes.

This hybrid iris prefers full to part sun and rich soil with good drainage. Bearded irises make great cut-flowers and will help any old-fashioned garden shine!
