That's very interesting, Alberto, because traditionally the scent of Viola odorata has been thought to somehow numb the olfactory senses. In other words, you get a whiff, but you are not able to detect the odor for long. If you hand the same blossom to another person, they will immediately be able to detect the scent - but only briefly. Hand it immediately to a third person, and the same thing happens. On the other hand, some plants described as violet-scented do not have this property of numbing the senses. The Sarracenia I mentioned, for instance, can be enjoyed over and over without a noticeable lessening of the scent. Maybe if you can send up some of your scented Argentinian Oxalis, you can send up some of those violets, too. : ) Jim McKenney
