Karen, I thought I was responding to a different thread and wrote over my previous response, which I thought made little sense to this discussion. But then I saw your reply and realized lots of folks put the tags directly into their gardens so I could have just left it there. Sorry for the confusion.
Zuzu, so what would be the most reliable on-line resource to be sure the spelling is accurate? Not trying to be a pill, actually trying to make your life easier. As I understand it, the Catalogue of Life doesn't list cultivars, correct? Maybe that Missouri place? I don't even know what that is other than I have it bookmarked as a good resource.
