You will love it. If you want one that is more cold hardy, you might look at Arp.
Rosemary (Salvia rosmarinus 'Arp')
Or perhaps one to keep in a container where you could move it in for the really cold nights.
I had two nights in a row here at 13 degrees. The trailing rosemary (in a raised bed) did not have a problem.
Just one more Salvia...
