All of the Louisiana irises are already listed in the database, IF they are wild species or registered cultivars (through 2013). We have some unregistered cultivars in the database, although it's impossible to have them all, simply because there's no obvious way to find all of them.
I can add Lois Yellow to the database if you want, Cat, assuming you have pictures or information about it that you are willing to add. I don't like to create entries for unregistered cultivars if they are just going to sit empty forever. But, if people are actually growing them and want to have them listed the database, that's easy enough to do.
