We admire flowers for the beauty and alluring scents they bring to our personal and public landscapes. Flowers are a matter of pride for gardeners, a means of expression for lovers and they play a role in some of our most joyous and somber societal rituals. But to the plant, flowers are a deadly serious business. The plant’s survival depends on the appeal of its flower to a distinctly non-human client list. Sensory stimulating petals and odors have one purpose: to draw pollinating insects and animals to the plant’s reproductive organs, the stamens and pistil, housed inside the flower.
