Bonnie, Its a lot of plants and would be a lot of work. The owner says they are all more modern/current irises no historical ones. Bonnie, I am not exactly sure why potted, but I think its cause most of the sales are done locally and people pick up the plants in person.
Liz, I don't have the room at the house, I would have to go out and purchase a property to work from.
If anything I might get a couple of each for my collection for when I am more in a spot to able to do an iris farm.
