The Science of Fall Leaf Color
Hunnewell Lecture Hall, Arnold Arboretum, 125 Arborway, BostonThe Arboretum becomes a riot of color in October, with leaves turning deep red, fiery orange, and bright yellow. Have you ever wondered why this happens every autumn? Outdoor Educator Ana Maria Caballero will take us through the science of fall leaf color, including an exploration of pigments and abscission, a hands-on experiment to reveal the array of pigments present in every leaf, and a walk in the landscape to take a closer look at leaves in all phases of color change.
