I really like this one, enough to have bought three of them so I could have it in three different parts of the garden. The first couple of years I had it, it would die back in winter, but it always came back in spring. It didn't die back at all last winter, though, which was exceptionally warm here. It looked as good all through winter as it had the rest of the year.
I wouldn't call it drought resistant, but it's not a water hog either. It also has a less pronounced sage aroma than many other salvias, which sometimes smell too strong for my taste.
