Before my wife and I married she attended a culinary school. She relayed a short story to me about one day of class, preceded by the question, "What are those trees outside my classroom window?". In her words, The professor entered the class gave the day's assignment and put the students to work. As they gathered their supplies he queried to them, "Has anyone smelled those trees out side?" My wife replied by saying, "The one's that smell like fish!" The professor agreed and I knew without even seeing the trees that they had to be 'Bradford Pears'! I hate those trees!
This posting brings to mind the drug industry and how it relates to the 'green' industry. Drug companies and horticulturalists introduced products into the market and only years later do they find out the damage they have caused.
I have no clue as to why comments are made about how much the flowers stink. It's not as if I'm unable to smell anything at all. They just don't have much of any kind of scent to me & my husband. Neighbors who have Bradford Pears have never complained about the odor either.
