For a description of numerous cultivars of Iris cristata, including white forms, see Cole Burrell's article in the spring 2006 Rock Garden Quarterly. When I was developing this feature, I was surprised to learn there were so many available. I hope to acquire some of them soon, even though it's a constant struggle to keep slugs away from Iris cristata and its relatives here. Our native Evansia (crested) species, I. tenuis, appears to grow just above the "slug line," barely up in the elevation where snow lies all winter most years -- the next ridge up from my home.
