From this article about the history of flowers:
"Before flowering plants appeared," says Dale Russell, a paleontologist with North Carolina State University and the State Museum of Natural Sciences, "the world was like a Japanese garden: peaceful, somber, green; inhabited by fish, turtles, and dragonflies. After flowering plants, the world became like an English garden, full of bright color and variety, visited by butterflies and honeybees. Flowers of all shapes and colors bloomed among the greenery."
It took awhile of course, way back in the Cretaceous period, for flowers to arise, but they surely did. We would not be if not for them, and the world would no doubt be less colorful, though of course I have a quibble with the person who decided the earth was somber prior to flowers. How does he know?
The citizens of the District tend to always be somber, even when everything is in bloom - though - at this moment in the season, it's a pretty hard to stay somber if you're outside in the colorful riot of cheer that marks our midatlantic spring.
No one know exactly how - or why - the green world began wrapping its seeds in fruit, but it did, thank goodness! Complain as I sometimes do about being overwhelmed by all the colors and shapes, because seriously it is overwhelming, I am enchanted, drawn in, and every year freshly amazed at the beauty that pops up then spirals open here in this fertile swamp.
Bless the flowers, bless the bees, bless the trees. Cheers!
