Yes.
I don't pretend to know much about how this stuff works, but have used Haunted Heart as a parent enough to say with reasonable confidence that if you cross it with a red iris some portion of the seedlings, maybe 10% or so, will be greenish. I think I understand why, maybe.
On the SDB side, Stop and Stare also reliably throws green seedlings. I have no idea why, other than there's obviously some genes for yellow hiding in its DNA because it also throws a boatload of variegatas, no matter what you cross it to.
