Reblooming German Iris Immortality

Reblooming German Iris Immortality

A popular and vigorous rebloomer, Reblooming German Iris Immortality brightens gardens and vases with fragrant, pure white blooms with light lemon-yellow beards. Whether planted in masses or paired with other colors of iris, Immortality adds elegance to the garden when it blooms in mid spring and reblooms in late summer to early fall. Its green, swordlike foliage stays attractive for months. Growing 29" tall, this hardy perennial resists drought, disease and insects. Deer tend to pass it by. For the best results, plant iris rhizomes in full sun to partial shade.

Botanical Name: Iris germanica 'Immortality'
