Sherry, you had a double post for Salvia leucantha 'Santa Barbara' so I went to delete just one post and it deleted your image in the second post too, not sure what happened there. Can you please repost it? When you do, I'll delete the one with the missing image. Sorry about that, must have been a glitch.
Costa Rica Blue is one of my favorites, I took a cutting of my huge one out front and have another one planted out back next to a climbing rose.
I used to have salvia mexicana, it got too big for the area and then I lost cuttings from neglect. It's such a beautiful color!
