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.

The Immortality bloomed this year and the plants are incredible. The first year the leaves were there and the plants were healthy, however in 2021 they are multiplying and blooming profusely. Huge flowers!

- Q
I purchased an Iris Germanica "Immortality" locally last June. I live in Canada. I knew it was past spring bloom time when I bought it. Ok so far. This spring it bloomed a Lilac/Pink & White bloom. The local garden center, where I bought it told me it had reverted back to its original colour. What are the chances of this happening? I am doing some research to answer this question. If you can help me, I would appreciate it. If you cannot, please let me know of someone who could.
- Asked by Rene
- Verified Reply - AngelaTo my knowledge, Irises don't revert and change color. There can be some slight variations due to sun exposure, stress, temperature and age of the bloom. Generally, Irises don't change color.Was this answer helpful to you

- Q
What amendments shd I add to soil when planting? and What fertilizer is recommended? Thank yoy
- Asked by Celia
- Verified Reply - ViciWhen planting bulbs individually, use 1 Tbsp. per bulb and mix thoroughly with soil around planting hole before placing bulb in. Bearded irises in poor soil respond well to a light application of fertilizer in spring as new growth starts. The fertilizer will support blooming and health without encouraging the growth of extra foliage. Spread the fertilizer around the rhizome rather than applying it right on top, because direct applications can burn the rhizome.Was this answer helpful to you
- Q
Will the iris bloom next spring?
- Asked by Iris lover
- Verified Reply - ViciThese are shipped and planted in the fall. It's entirely possible you will get some blooms in the first season, but usually, this first year is spent developing a robust root structure that will fuel an eruption of flowers in the second full season after planting.
