I'm a person who's visually biased- maybe most of us are. Our garden is truly a visual delight. But the visible is every day. Once in a while a garden aroma hits you that brings to mind words like "heavenly," "sublime," or "intoxicating." After a long winter indoors, nursed along by Janet at the foot of her potted Meyer lemon, the Nicotiana has come into full bloom. The lush, rich, ephemeral, transcendent fragrance of this mysterious flower is indescribable.
