Spring Hill Nurseries Immortality Bearded Iris

Unlike standard irises that flower only once in spring, the Immortality variety is bred to produce a second flush of blooms later in the season. You can expect a reliable display in mid-spring, followed by another round of white flowers as the season progresses.

While it can tolerate partial shade, this iris performs best in full sun. Aim for at least six hours of direct sunlight daily to ensure the strongest stems and the most prolific reblooming cycle.

Yes, this is a hardy perennial suitable for zones 4 through 9. It is quite adaptable to various climates, though in the coldest zones, you should ensure the rhizomes are well-mulched before the first hard frost.

You can expect these to reach a mature height of approximately 29 inches. Their sturdy stature makes them ideal for the middle or back of a garden border where they can stand tall without needing constant staking.

Leave the foliage intact after the blooms fade, as the leaves are essential for gathering energy to support the plant's next flowering cycle. You can trim back any yellowing or damaged leaves, but avoid cutting the plant all the way to the ground until late autumn.
