Orchids are seducers. They trick animals into pollinating them and usually give nothing in exchange. Some orchid species mimic nectar-producing flowers to lure bees; others emit the fetid smell of rotting meat to attract carrion flies. In China, Dendrobium sinense orchids release a chemical normally broadcast by bees in distress; the scent attracts bee-eating hornets expecting an easy meal. The scent of Cymbidium serratum entices a wild mountain mouse, which spreads pollen from flower to flower with its snout. And around the world, orchid species have evolved to look or smell like female insects; males try to mate with the flowers but gather and deposit pollen, which they carry on their flight from deception to deception.
But perhaps the most spectacular evidence of the plant’s powers of attraction could be seen several weeks ago in Singapore, at the 20th World Orchid Conference, a triennial affair that drew about 1,000 participants from 55 countries and more than 300,000 spectators. It was one of the largest orchid competitions in history, a colorful, heavily scented affair that showcased the growing popularity and cutting-edge science of orchid breeding. (...)
Orchids may be the most diverse flower family in the world, with more than 25,000 species. (Their only competition comes from daisies.) The orchid family maintains such diversity in the wild in part because individual orchid species summon only specific pollinators; the flowers thus avoid mingling their genes with those of other nearby orchids that are visited by their own pollinators. But most of the 50,000 orchids from 5,000 varieties on display at the conference do not occur in the wild; they are hybrids, created by people who have cross-fertilized orchid species, often from far-flung lands.
“The joy of breeding orchids is to see if you can combine two species in order to create something even more beautiful than either of the parents,” Martin Motes, a commercial grower from Florida and conference judge, said as visitors poured into the hall and crowded around the displays. He has been breeding orchids for 40 years, and many varieties of his 500 hybrids are named after his wife, Mary. “My wife thinks I am playing God! Well, man is given dominion over the beasts of the fields and orchids of the greenhouse, I guess,” he said.
