Several iris and daylilies share names, and that's part of why I now color code my nametags. I've pulled up daylily tags, thinking a plant was mis-named, when really the tag was referring to the iris next to it. If i were really organized, I would add the hybridizer name on the tag, and that would be a clue, but Niswonger and Maryott do both, so even that is confusing.
