Reblooming Iris germanica


By siris


Iris germanica “Immortality”, is a remont that is, it can, won’t say will, re flower after the normal flowering period in Spring.
Pictured below , is part of a row of Immortality, flowering on 12 August in the walled garden at Osborne House. There must have been at least 20 clumps in the row.
One of my clumps of Immortality flowered last year in about November and then all clumps flowered this spring. There needs to be a sufficiently large secondary rhizome for the clump to re flower as the flowered rhizome shrivels up after flowering. I don’t think therefore mine will flower again this year, although I have fed them well, blood ,fish and bone.
Would be interested to hear of others’ experiences of re blooming in the UK. It seems to me that the expectation is better than the reality!

i never knew that there were re bloomers so ive just looked up about it and the information which i read
included “Immortality” as being one of the best re bloomers! but also there are a few others to choose from
:-) therefore i may give one of the others ago:-)
it would be nice to have iris bloom a bit longer or different times of year as the blooms i like to see very much on those grand upright stems.
can not help with the imformation you enquired for but grateful for the blog for reasons mentioned.
thank you :-) hope some other members on GoY have
“Immortality” .

I don't think re blooming is very reliable in the UK, but I have read that they are usually reliable strong varieties, so maybe that's a reason to grow them.

It's nice to see things blooming again, even out of season :)

I've had Immortality for quite a few years now and it's only ever rebloomed for me once a couple of years ago in think it was October!!!

Inside the walled garden at Osbourne was a real sun trap and obviously very fertile. October and November are too cold and late for the flowers to stay long, me thinks. A waste of time and plant energy.
