Anthony,Marcus Harvey from Hillview Rare Bulbs in Tasmania has it on his catalogue periodically. That is Iris iberica ssp elegantissima at least. Is that what you're after? It would need to change hemispheres, but if you can't find it anywhere else there is him at least. He usually sends out his catalogue just before Christmas, and does sell overseas. I can provide contact details if you (or anyone else) wants them.
