Iris germanica ‘Immortality’
Blooming Time
Exposure
This classic selection has such a fantastic reblooming presence that it’s nearly everblooming, bearing large pure white blooms mid to late spring and again in early to mid fall. The ruffled white flowers are embellished with pale yellow beards and exude a strong sweet fragrance, making them excellent in cut bouquets. ‘Immortality’ displays excellent vigor and will spread to form large clumps of tall, architectural sword-shaped foliage within a few growing seasons. ‘Immortality’ is a great addition to cutting gardens and sunny perennial borders.
