Seed parent: Moraea aristata
Pollen parent: Moraea loubseri
Cross a white Moraea with a purple Moraea and what do you get? A pale purple Moraea, duh. These are vigorous plants that put out many flowers, but they're not all that exciting visually. They're also completely infertile so far: 0 for 9 as a seed parent, and only one attempted cross as a pollen parent because the flowers have virtually no pollen (the cross failed). I'm afraid this particular cross is probably a dead end for breeding.
It does raise an interesting question, though. In terms of shape, the flowers below look a lot like the flowers of MM 99-00, a cross that I thought was between M. neopavonia and M. atropunctata. I wonder if those bulbs might actually be M. neopavonia x M. loubseri. I am repeating both crosses to find out.
Anyway, here's how the flowers look when they first open:
After the flowers have been in the sun for a few days, the tepals fade to almost pure white:
