According to "Iris of China", the type specimens of both species are Siberian plants. I don't know how far north into Siberia the species extend. Some people have suggested that they might be better classified as variants of one species, but I'm not sure what the experts currently think. The seeds of both species have a curious structure, see the SIGNA database:

Ken,

I see what you mean about I. uniflora. I wonder which is hardier, it or ruthenica. The iris is growing at a friends place in zone 2.

It does look like a pretty good fit for I. ruthenica. The ones I've grown have very short stems, while I. lactea normally has quite long stems, particularly as it gets well into its bloom cycle like the plant in your photo. The leaves are also more consistent with I. ruthenica (I had to identify and ignore the several blades of grass in the picture). I. lactea has long, rather narrow, thick fibrous stiff leaves. The two varieties of I. runthenica that I've grown do have falls that reflex more as the they mature than what I see here, but I did get a clone of I. ruthenica's very close relative, I. uniflora, to bloom once and my pictures show a flattish bloom.

I'm attaching photos of the red form of I. ruthenica, I. uniflora, and the I. lactea I have which is closest in flower appearance to your photo.

Thanks all for the replies. I think I have identified it as I. ruthenica.

My first guess would be I. lactea also.

My first guess would be I. lactea, but the flower parts are a bit wide. How tall is it?

Can someone please tell me what species this is?
Thanks,
