Anthocyanins
Backyard Wisdom - September 2017
Gilbert A Smith, ISA Board Certified Master Arborist
Can you see the red color of the spring foliage on this Burr Oak? It looks like fall color and in fact this is the same dynamic that goes on every fall. The color is a pigment called anthocyanin, which is responsible for red and purple fall color. But what is it doing in the young spring leaf tissue? Red Anthocyanins are one of the 3 plant pigments.Carotenoids providing orange colors like carrots and chlorophyll, which we all know, is green. These three pigments are present in leaves all the time but the green from chlorophyll usually dominates.
