A few years ago I'd witness 3 German Shorthair Pointers demonstrate their sense of smell. The three had just been left out for a romp around the yard. Simultaneously the 3 slammed on the brakes, made a quarter turn and locked on point with noses held high.
Obviously they all smelled something, but I had no idea what it could have been. Some fragrance carried in the wind.
I have been snooping the recent postings about fragrant hostas, and today hostas whose flowers appear below the leaves. So I started thinking, and when Theresa thinks she becomes dangerous.
What we mere mortals feel is fragrant is not likely to agree with all nature. In fact we have a relatively limited sense of smell. Those 3 GSPs certainly didn't agree with my concept of fragrance. Put them in with a 4th and a whole lot of butt sniffing would take place. Must be fragrant to them but not to me, in concept (because I would never get close enough to smell that they do and don't even know if I would recognize it if I did).
My point is that I expect that ALL flowering hostas are fragrant, but some we don't have the ability to smell. I am sure the hostas with short scapes attract pollinaters that are attracted to the flowers below their leaf canopies. For whatever reason, it has become their characteristic.
Does anyone know if my assumption is any way near right, or can give me more insight?
