Its a highly domesticated cultruigen herb that can only be grown with cuttings, from others, and replicated that way. If you find a seed the likelyhood of it sprouting is slim. As far as from what i've read.
I've never been into a head shop that had anything related to plain leaves, or cuttings....lightly likely, but if you do find them then yes, you can grow it, just as you could with pot......cuttings work.
just google salvia plants ... you really dont want plants its too much of a hastle to take care of and not enough leaves to do much with .. i got 2 salvia clippings for 40 dollars ..
If you planted a salvia seed itd take two years at least for a half decent crop man lol and like the others said salvia seeds are incredibly rare as they rarely flower. If you insist on growing it then buy a cutting. But the growtime/ electricity isnt worth the harvest. Your best bet is buying large amounts of dry leaves off of eBay or somewhere and making extract yourself.
