I've lost the tag to this one, but it's either 'Sea Heart' or 'Silver Heart'. Whichever it is it's a vigorous grower. I ordered both and they do look a lot alike to me! This one is in full sun until mid afternoon and is doing great here. Not too much damage for this time of year. I've even divided it because it was getting too big here.
Here's another that's in more shade
Alexander's Great is a slow grower for me, but it's still looking pretty good for August.
