Flowers Against the Stereotype

Many a poet has drawn upon the delicate beauty of flowers for literary inspiration.  The softness of the petals.  The sweet fragrance.  Flowers thus lend themselves to being a symbol of femininity. (Also, notice how in our U.S. culture, women will be given a corsage to wear vastly more often than men are given boutonnieres.)

Here are some poetic examples of flowers in an inspiring role:  Shakespeare's Juliet, in the balcony scene of Romeo and Juliet, depicted herself as "a beauteous flower."   Alfred, Lord Tennyson connected the physical characteristics of a flower even more explicitly to those of a woman, writing:
"Lightly was her slender nose
Tip-tilted like the petal of a flower."
The 19th-century German writer Heinrich Heine went straight to the point, titling one of his poems "Du Bist Wie eine Blume," which translates to "You are Like a Flower."

Hard to believe it's a real flower!I wonder what such poets -- who thought of flowers as being delicate and feminine -- would have thought about a flower from Sumatra that I heard about on the radio. Far from sounding feminine, it was described as being "like a giant finger jutting straight up... eight feet tall and [weighing] 250 pounds."  Nor would a person want to extract the essence of the aroma this flower gave off, because it had a "distinctive rotting-corpse-like odor."  The evolutionary explanation behind that flower (scientific name Titan arum) is that the putrid odor enables it to attract insects who believe they are coming to the carcass of an animal on which they might feed.  The insects flocking to the flower get tricked, while the clever flower gets itself pollinated.

It was not only insects who have been disappointed in the case of this particular flower, which was on display at the U.S. Botanic Garden in Washington, D.C.  Many of the museum-goers who flocked to the flower, hoping to get a whiff of its repellent odor, were disappointed because the colossal flower emitted its odor for only a few hours, and did not have the courtesy to schedule its opening so as to align with the museum's daytime hours.

The finger-shaped Titan arum is not the only tropical Asian flower to have evolved such a trick of deception.  Another species, the Rafflesia arnoldii, has a more typical floral shape, being circular with petaled edges.  But it is similarly oversized (two or three feet in diameter) and also smells like a carcass during part of its blooming period, even if only briefly.

I was not among either the disappointed or the pleased museum-goers at the U.S. Botanic Garden. Nevertheless, I take delight in that news story about the non-stereotypical flower for two reasons.  I take delight first in being reminded again about how evolution, with all its immense variety, has developed a living being that defies our human expectations, particularly our cultural associations.  Secondly, I am pleased to hear that so many people can themselves take delight in an example of biodiversity that we ourselves would not have designed, and might have usually found repulsive.

Do you have any thoughts about these huge, putrid flowers?

Life-Giving Corn

When I was a child, my mother would usually allow me in the kitchen while she worked. More than allow -- she often seemed to like it. She endorsed the motto of "learning by doing," inspired by the early 20th-century educator John Dewey.  When I was young, there was not much I could do by myself in the kitchen except watch up close.  But occasionally, there was a task I could do all by myself: shuck the corn.  However, she sent me outside to do it, knowing it could make a mess.

I would first open several sheets of newspaper, and spread them out on the driveway (the way I had been shown).  That would make it easy to fold up the discarded parts of the corn into a large wad that could be tidily dropped into the trash.  It was pretty easy for me to pull off the green husks and most of the long "hairs."  (Only once was I startled by a small, now dead caterpillar that lay neatly in one of the rows of kernels.)  It was a bit of a chore, however, to try to get rid of every last one of those "hairs" on the ear of corn.  I might have been appreciative of those silks if I had know that it was through them that the cob of corn had been brought to life, those strands being the upper female part of the plant's flower.

Over the past decades in the U.S., corn has been mentioned in the media mostly in regard to concerns about the amount of corn syrup in processed foods, or about the drawbacks of using food such as corn (rather than something like switchgrass) to make ethanol to add to gasoline. About the only time corn gets mentioned with exuberant appreciation is in the patriotic story of how in 1612 Capt. John Smith's ill-equipped Virginia colonists were saved by the bushels of corn they received from Native Americans.  And so, I'd like to speak a good word for the often overlooked corn (which is called "maize" in most of the world).

A stand for corn. (No puns, please.)

Those Virginia colonists were not the only people whose lives have been saved by corn.  When Columbus landed in Cuba, he found the production of maize going strong.  A similar discovery was made by Francisco Pizarro in the early 1500's.  The Inca nation (whose leader Pizarro captured) was vast:  2,200 miles long and containing nine million well-fed people.  Their lives were to a great part sustained by maize.  Even though corn contains little protein, its advantage over the world's other major grains (wheat and rice) is that it can be simply cooked and eaten without having to process the grain.

Moreover, the "sweet corn" bred for human eating is but one category of maize.  Even the Native Americans had field-corn as well for their domesticated animals (which in turn supported human life).  And they had flour corn, whose kernels are more suitable for making flour.  Not to mention that enduring cinema attraction, popcorn.

All these types date back to a form of wild grass in the Zea genus, whose seed-ear is minuscule.  Human cultivation enlarged that seed-ear.  The great chain of human life living off cultivated corn throughout the world has been traced back by archaeologists over 7,000 years!

Do you have any childhood memories involving corn?
