Species cross irises

Here's a clump style picture of three seedlings of Iris cengialtii LOPPIO x Iris reginae. I'm using the blue-ish one on the left as pod parent and putting pollen on it from a seedling I call "ruffled sib to aqua".

Below is a picture showing the traces of "turquoise" that I'm hoping to intensify and exapnd on. I removed the standards so you can see how the style arms of "ruffled sib to aqua" (left) compare to one of the bluest typical type irises (on right).
