Would someone be able to identify this very-late blooming iris? I photographed it at Longwood Gardens on June 18 in a sunny garden, far from any body of water. I was amazed to see an iris blooming this late in the season.
The foliage is variegated and the flower scapes are about 3 - 4 feet tall. A Longwood gardener thought it was a Siberian iris. My Siberian irises finished blooming several weeks ago, so I would love to know what cultivar this is if indeed it is a Siberian. I read that Japanese irises bloom later than Siberians, but tend to grow near water.
Thank you.
