We're getting repeat stalks on five diploid beardeds here:

So far, blooms have opened on two seedlings of CLOWN PANTS x Iris pallida Latil
and the unregistered sibling of CRICKET SONG and EASY SMILE garden named "Smiley's Sister"

CRICKET SONG and "pink volunteer" both have one stalk each that should open in a day or two.

Here are pictures of the two CLOWN PANTS x pallida Latil seedlings
and "Smiley's Sister"

I'll post the others when they open.

You can see bigger versions if you click on the pictures at my blog:
