Too blue!

I think this is a blue flag iris (Iris versicolor). They're all along the edge of our pond and have just started to flower. Between these, the bluebells, cornflowers, aubretia, ceanothus and forget-me-nots, which are all now in flower, our garden is far too blue, though, and I'm looking forward to my big red poppies flowering in the next day or two!
