I have this too, never noticed stinky leaves. I have, purple,pink, and white. It is as Baa says, salvia horminium or I recall the term salvia viridis. Have you heard this term ,Baa? I bought my seed from Chiltern's.
It is my understanding that the true clary sage is Salvia sclarea. Hugh green leaves at the base, biennial, very similiar to Salvia argentea, reseeds as far as 20 feet. I haven't had Salvia argentea reseed, but it will grow 'out' from the base.http://www.grovestreet.com/jsp/onepic.jsp?id=73105
This is the perennial problem with Common Names, they don't belong to just one plant. There can be no such thing as a true Clary Sage since, as we see here, at least 2 plants hold it as a widely known common name.
