My is more northern , While I have had Hummingbird sage , lady in red , self sow here , That happens rarely and very few , it is a more hardy plant were you are
We get that freeze , thaw warm spell action weather also ,, That warm back to freeze makes it tough on a lot of seedlings ,
Very few Salvia will overwinter here ,
Even the Mint type sage has difficulty here ,, I would say try march with a few seeds just to try , and as above ,, your usual spring sow might be better , and probably .
A few Biennial type Agastache is usually all I get to return ,
