My guess is none of them. Salvia d. is generally only found as a clone of a few plants, which means you'd have to buy a clipping. Salvia d. has an extremley low turnover rate from seeds. Ultimately, this means you would of had to either buy a clone or buy a lot of salvia d. seeds and if it you did buy the seeds you wouldn't see a discrenpency in the plants...

I think it is just another salvia speices (prob. on of the mintier ones).
