Lily of The Valley Phenomenon
See also: bourgeonalThe odor of lily of the valley, specifically the ligand bourgeonal, attracts mammal sperm in a dramatic manner. The 2003 discovery of this phenomenon prompted a new wave of research into odor reception, but no evidence was found that the female sex organ has similar odors of any kind. A 2012 study demonstrated instead that at high concentrations, bourgeonal imitated the role of progesterone in stimulating sperm to swim (chemotaxis), a process unrelated to odor reception.

“I am the rose of Sharon, and the lily of the valleys.”
—Bible: Hebrew The Song of Solomon (l. II, 1)
“It is not growing like a tree
In bulk, doth make man better be,
Or standing long an oak, three hundred year,
To fall a log at last, dry, bald, and sere:
A lily of a day
Is fairer far in May
Although it fall and die that night;
It was the plant and flower of light.
In small proportions we just beauties see,
And in short measures life may perfect be.”
—Ben Jonson (1572–1637)
“There has fallen a splendid tear
From the passion-flower at the gate.
She is coming, my dove, my dear;
She is coming, my life, my fate;
The red rose cries, ‘She is near, she is near;’
And the white rose weeps, ‘She is late;’
The larkspur listens, ‘I hear, I hear;’
And the lily whispers, ‘I wait.’”
—Alfred Tennyson (1809–1892)
“In a valley late bees with whining gold
Thread summer to the loose ends of sleep....”
—Allen Tate (1899–1979)
“When the ice is covered with snow, I do not suspect the wealth under my feet; that there is as good as a mine under me wherever I go. How many pickerel are poised on easy fin fathoms below the loaded wain! The revolution of the seasons must be a curious phenomenon to them. At length the sun and wind brush aside their curtain, and they see the heavens again.”
—Henry David Thoreau (1817–1862)
