Nathaniel, everywhere I look it is Mint Marvel is shown as 'Mrs. Giuseppi'. Here in our database, Sempervivum-Liste.de and Mountain Crest Gardens also sells it under both the Mint Marvel name and on the back of the tag it is 'Mrs. Giuseppi'.
@goldfinch4 Chris do you still have that one? If so what does your tag show?
Here we go again. I wonder who it is that has registered that trade name? SUPERSEMP®
