Hi everyone - I am a regular on the winter sowing forum, but decided to visit you because I LOVE salvias. I got some Salvia Black and Blues on sale at Lowe's and wondered if they come back here in NC - we can get pretty cold here but the ground very rarely freezes - Thanks for any responses - Carrie (also is the Blue Bedder an annual? Splendens? annual? thanks) (...PS I have a lot to learn about Salvias)
