I didn't think they did, but when I did a google search to check for you, I found some links that sell the seeds, so maybe yours will reseed, but to be on the safe side, buy fresh seeds for next year.

I followed their instructions and had beautiful Salvias all summer long. They have a great Youtube video that was extremely helpful:

You start the seeds about 8-12 weeks before your last frost (not sure he says this in the video, but I picked it up somewhere and it worked perfectly) so I'm getting ready to start mine today or tomorrow. One other thing I can add is that in the video he says to use a fine crushed granite to cover the seeds-I found that baby chick grit worked perfectly.
