Actually, talking about live plant and seed vendors is OK according to the attitude, as long as they are legal. With Salvia, legality is very different in the various countries, idk the status in Israel. It's legal in Holland, which afaik is where this site has its physical and legal home.
Anyway, i don't have any better tip than looking through the
Sustainable plant and seed suppliers. Don't use Arkham's, they became unreliable/defunct a while back.
