Have you seen it bloom? I would guess one of the gold hyssops/agastaches.

Hmm, images of Gold Hysops do look like the same kind of leaves, but I don't recall it having showy flowers as shown in some of the google images. I'll have to pay closer attention this year.

Thanks.

Do you remember which vendor you got it from?

I don't. It was a young woman, that's all I recall. This was 4 or so years ago.

Oh, I think that's it. I'll know for sure when it blooms as the flowers I saw look like what I remember. Not showy like the agastaches. Hmm, I may need to get an agastaches.
