Greg, are you going to enter SS in the database? Dave and I had talked about entering unregistered irises when the database first started if there was a reason to. And I think this is a good reason, it's actually a name your friend gave it, and you are sharing it with others. If you think about it, a lot of plants are not registered.
I would put the story under remarks why it has that name, and why it's never been registered, but I would put it in the database.
