Fall in New England is spectacular.

As the nights are getting colder and the sunlight hours shorter, trees begin to prepare for winter.  Their natural practice of photosynthesis (taking carbon dioxide from the air, water from the ground, and light from the sun and turning it into oxygen and glucose) begins to slow as their resources dwindle.  Therefore, they start producing less chlorophyll (what makes leaves green) and the reds, oranges, and yellows from the anthocyanin and carotenoid pigments show through.

Some large shade trees with fantastic fall color are Beech, Ginkgo, Maple,  Sweet Gum and Tupelo.
