That's exactly what they are supposed to look like, the "Oh no, I killed them". In about 2 or three weeks, right smack in the middle of the dead looking fans you will see a tiny green 'pointie' starting to grow. Before you know it, small fans will appear.
Every year when I give out Iris to people who never grew them before, I tell them about 2 weeks after they plant them, they will look dead. It's funny because every year they say the same thing, "I thought I killed them, but then they started to grow".
No worries mate, they are fine.
Blessings
