Does anyone here know of the various types of Artemisia?

I grew some years ago and brought the one I loved from CA to OK and it died when I tried to transplant it again. It was not a ground cover but grew from one bush and grew big. In the summer when it bloomed the only way you could tell was when your turned the leaves over they had tiny yellow balls on them. The woman who grew it in CA said that she thought it was a silver queen or silver king, but I can't tell by looking at the photos. this one grew about 2 to 3 feet high and just as wide. I want to order it this spring but don't want a ground cover. I know it was not dusty miller or mother wort but it was large like mother wort. thanks.
