The Science of Fall Leaf Color

The 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.

Accessibility: This program includes a short walk over pavement, grass, and gravel.

Audience: This program is geared towards adults.

To reach the Arboretum’s Arborway Gate and the Hunnewell Building, continue along the sidewalk on the Arborway to the Arborway Gate (about 12 minutes), or go through the gate, bear right at the pond, and continue to the Hunnewell Building, which will be on your left. The Lecture Hall is located inside the Hunnewell Building.

Take the #39 bus to the South Street @ Bardwell Street stop in Jamaica Plain. Walk down South Street away from Bardwell Street, take a right on Custer Street, and walk down Custer Street until it ends.
