Can you help me to identify this iris?
It's a Siberian but I don't know which cultivar.
Definitely Siberian, as iris_gal stated ... seeing a view from the side might help a bit, since it's hard to see their height from the current angles.
I discovered what exactly this iris is by chance - walked into the garden centre and found exactly the same irises sold there!
I read the label - it is Dwarf Arctic iris (Iris setosa var. arctica)
Here is a link that might be useful: Dwarf Arctic iris
Setosa!!! Was I ever wrong. Glad you found its name.
