Science Behind Colors
Transitioning into short autumn days with lower temperatures limit available photo-energy needed to produce chlorophyll. Some leaves have managed to retain their green pigment due to the abundance of chlorophyll collected over the summer months. However, as the storage of this chemical depletes, other pigments begin to appear across the leaves of American canopies. Gingko trees are just one of our many favorite species to watch transition.
