I've had that blooms like yours on newly planted iris.
Is your name "Naty" short for, or a nickname for Natalie??? My little sister is named Natalie and I sometimes call her Naty or Nat.

And thank you for posting that question. Yes, an iris will bloom deep in the foliage occasionally, due to stressful weather conditions. Many time the weather warms up, then goes close to or down to freezing, then warms back up again. They are so large and stiff, they are not so flexible as other plants. Many times the leaves will be adversely affected as well.
Lucy gave good advice to cut the stem of the flower and wait until next year.
