Tough plant! Medium-height perennial with finer foliage than its larger-flowered cousins. Flowers come in many shades from white to dark blue; ours are light and dark blue. The ones in the photo on the right, at about 3 ft, are by far the tallest of the ones in our garden - most of them top out at about 18".

|Ben Hamilton||Apr 27, 2009||When is the best time to divide compacted clumps??|
I do so in early to mid spring - they bounce right back then.
|Kathy||Jul 07, 2009||Hi my iris turned out to be white ( I really wanted the blue!) so I was glad to read on your site they can be white before I headed back to the garden centre to create! would still like a blue one though, I planrted it against a white wall so it doesnt show up|

|Kate Edwards||May 19, 2010||I have 3 huge clumps of Iris Siberica in my main boarder. Please can you tell me why my Iris sibirica is not flowering. The first year they were spectacular but the following 2 years very poor and this year none. Clay soil, damp, plenty of sun in herbaceous boarder in Herefordshire. Kind regards Kate Edwards|
Hmmm, I really don't know. Mine are planted in areas with different exposure, from mostly shady to full sun, and from fairly dry to more consistently moist. All do well year after year. It can't hurt to divide them and see if that returns them to blooming.

I have 2 huge clumps - one in part shade (at least 30 years old), and the second one in full sun (about 20 years old). Both do equally well - I've taken chunks off the edges to give away but they've never been dug up. It seems as though when I dig up a chunk, the plant expands even more. Both bloom prolifically - same color as your photos, and neither have any problems with bugs or disease. The foliage stays green after blooming so makes a nice background plant. I would recommend this plant to anyone. I've also acquired some Siberian Iris Cultivars in the last 7 years and am equally impressed with them.|

|Molly||Feb 01, 2023||I'm glad to see I'm not the only one with shorter-than-reputed Siberian irises. When I see estimates of 3 and even 4 feet, I believe that happens, but it sure doesn't happen in my garden. I also get much floppier foliage, though, so it may be an issue of not quite enough sun for their taste. They certainly flower and spread very cheerfully, though!|
