When I got a message that I had 'Rosemary' salvia in my Plant List and invited to post a comment to this thread, like Pod and Marilyn, I was initially confused. Then I looked in the database and noticed the synonyms and realized that it's been moved to the salvia genera.
I have grown 'Arp' outdoors for several years and it blooms faithfully each winter into spring. The tiny blue blooms are a treat to the eyes during the cold season. It's a good nectar plant and mine are usually still in bloom when the hummers arrive. It is fairly easy to propagate and I've shared cuttings/rooted plants with many of my gardening and culinary friends. It is delicious cooked with roasted meat and potatoes.
As mentioned above, it does get woody with age. Because both of mine where mangeled/
damaged when a large oak fell on them in the flower border during an ice storm a couple of years ago, I do need to think seriously about digging them out and replacing them. I'm going to root several cuttings to plant around my flower beds to deter rabbits and deer from dining on my plants.
