Design in Autumn Leaf Colors

In our neck of the woods, the autumnal equinox has just happened. The first day of fall...because that's what leaves on deciduous trees do. Some folks have fun admiring the autumn foliage, even taking trips to see it. They are sometimes given the silly epithet "leaf peepers."

Nature is not tied to solar or manmade calendars. Some trees begin the leaf color-changing process before autumn, others hang on to their leaves a while longer. Conditions are the guiding force, including stress. Leaves changing colors and falling is by design.

While scientists have a handle on the process, there is still much to learn. Since there will be less sunlight, the leaves that are used to catch it are burdensome. Before they are released from their duty, trees take back nutrients. There is no chlorophyll in the leaves, so their existing colors are revealed — except red leaves, those undergo a chemical transformation. This child suspects that the silent color show is also a gift to humanity from the Creator.

Scientists have long endeavored to comprehend the transformations that take place in trees and plants throughout the autumn season. While lacking complete knowledge, they possess sufficient understanding to explain the fundamental aspects of these spectacular displays. Interestingly, the colorful leaves are not only aesthetically pleasing, they also serve a crucial role in the trees’ survival.
