It was suggested on another forum that this might be Purple Dragon. Any way to be sure?

I just purchased 'Purple Dragon' and then add it to my plant list here. I always compare what I have to the photos posted and there are some that don't fit the description. So I did some looking elsewhere. I did find an interesting article on Lamium but it was before 'Purple Dragon' was introduced. (https://www.chicagobotanic.org...) I just looked for it's date of introduction, which might help you, but no luck. Here's mine. No flowers yet but soon. I hope there as purple as yours look.

Thanks. I skimmed the article. The name 'Beacon Silver' rings a bell and looks somewhat like mine. No way to be sure I suppose. So many of them look alike.
I have a nice plant and a nice landscape photo and can't be sure where to put one or what to tag the other.
