If it is truly an acuta, you should be able to clearly see venation. People are still selling verticillata as acuta, but verticillata lacks the prominent venation (it is still veined, but they aren't as noticeable) that is present in acuta leaves. What venation can be seen on the leaves of verticillata is a completely different pattern from acuta, as well:

I just picked up a cutting sold as acuta albomarginata and I can't really see any prominent venation but looking at the leaves in those pictures I'm thinking that it might be verticillata.

isde02, my verticillata albomarginata looks the same as yours. I love their leaves smooth waxy stiffness. It bloomed for me quite well this spring, the plant is just under a year old.
