Photosynthesis and Chlorophyll and just Plain Beauty!

Fall color in our part of Iowa is not nearly as vivid as farther east and north into Minnesota and Wisconsin. The variety of maples that generally grow here turn yellow or burnt yellow with only a hint of the vivid reds seen elsewhere. But there are a handful of sugar maples around town that turn a gorgeous red. On a sunny day they can be stunning. This one will be gorgeous when fully colored.

How do trees turn red and how do they know when to do it? You can read a simple explanation of that here and if you really want to play scientist, read this fascinating page.
Key words are photosynthesis and chlorophyll.
