Why Do Leaves Change Colors?

Why Do Leaves Change Colors?

Temperatures dropping and leaves changing color can only mean one thing… Fall is finally here!!

The Parklands of Floyds Fork is a great place to view natures changing scenery. As we transition into fall, we are welcomed with the warming array of colors that encompass us. From golden yellow, to crisp red, the Parklands provide many opportunities to see nature in a variety of hues.

Have you ever wondered why leaves change colors? What is the chemistry behind it all?

Let’s take a deeper look at leaves and what thrives under the surface:

Leaves have an abundance of chlorophyll found in chloroplasts, which are vital to photosynthesis. Chlorophyll allows plants to absorb energy from the sun. The wavelengths absorbed are red and blue, which causes the green wavelengths to be reflected; therefore giving leaves their green appearance.

Chlorophyll requires sunlight and warm temperatures to continuously generate new amounts of chlorophyll for the plant. As the nights get longer and sunlight decreases, the amount of chlorophyll also decreases. During this time, plants begin to conserve water and stop nutrient flow to the leaves. As a result, the chlorophyll breaks down and the leaves start to appear less green. The other pigments, that are in leaves year round, begin to emerge with the absence of chlorophyll. The two pigments responsible for the hues of fall foliage are Carotenoids and Flavonoids.

Check out this fun chart to learn more about each pigment and don’t forget to check out our lineup of festive fall programs this October (listed below)!
