Leaf Color Patterns in Aging Leaves
During aging and senescence the leaves of many temperate plants take on amazing patterns of color. This can only be discerned by looking very closely at the leaves. We have taken some very close-up photographs of many of the more common trees that change color at Harvard forest every autumn. You can also see how dramatically different the leaves of many trees and shrubs appear. Click on a picture to see a larger image.
Red maple produces extraordinary and contrasting patterns of color on their leaves during the autumn. These color patterns are seen at different scales.
Sugar maples produce more uniform colors in their leaves, and with more color production than other species.
In white oak, the surface character of the leaf is more subtle and more brick red, than the younger leaves of other plant species.
