For hundreds of years flowers have acted as symbols of our human emotions, being in love, sadden by death or just to put a smile on someone's face.
The practice of giving flowers reached its height in the Victorian era, when a whole symbolic language of flowers evolved.
But flowers have been used as gifts far longer than that, with evidence that people were presenting each other with bouquets as long ago as 3000 BC, and pollen deposits found at ancient burial sites dating from 100,000 years ago suggest the practice is even older.
Flowers make people happy. And while that might seem obvious, there hasn't been much research to prove the point until now.
A trio of new studies by Rutgers University scientists supports the notion pretty strongly, and the experts go on to speculate that flowers have flourished on this planet, with their beauty evolving in recent millennia, partly because humans are so attached to them.
The first study involved 147 women. All those who got flowers smiled. Make not: all of them smiled. That's the kind of statistical significance scientists love. Among the women who got candles, 23 percent didn't smile. And 10 percent of those who got fruit didn't smile.
Another study involved 122 men and women in an elevator who were given either a flower, a pen, or nothing. Those who got flowers smiled more, talked more, and here it gets interesting they even stood closer together.
Finally, in another test, bouquets were delivered by florists to 113 men and women in a retirement community. All 113 got flowers and a notebook, but some got them earlier and received a second bouquet when the others got theirs. By now you can guess the outcome. The more flowers, the more smiles.
From there, it's a bit of a leap to the idea that flowers are prolific because we love them.
People have been fascinated by flowers as long as we can remember. They are an emotional product. People are attracted to smells, sight and beauty and all of the above are in a single flower.
