mysticfoxtrot;
It would be a formidable task to keep such
information in one location. Due to elevation,species
weather all play such an important role in determining
what Salvia species growing in different conditions would bloom when.
IE:usda Zone 8 in California,Texas,Florida would all have different growing conditions in different years.
Hope I explained that clearly

Check out the 'New Book of Salvias' by Betsy Clebsch. She certainly does not have them all (pretty hard to do),but she's in Santa Cruz and knows how salvias grow in California. Your library probably has it. Also, you can glean info by checking what the various nurseries who sell salvias have to say about each one....check the website for Native Sons Nursery (Calif.), Digging Dog Nursery (Calif.), Canyon Creek (Calif., Nursery may be closed now, not sure, but website may still be up). Take a look at the Cabrillo College website about their salvia collection. Also 'California Gardens'...

Also...San Marcos Growers.
