Any who, I've never been a huge fan of fall color though some of the brilliant yellow and brilliant red trees have impressed me. These scenes are few and far between though and only last a few days before they're gone. What's happening here is that insects can't see red as well as other colors. The plants are purposely producing this pigment to discourage aphids from laying eggs around them. In this way they won't be the first trees infested with them come spring. How effective this is is debatable though especially with yellow being such a common fall color.
Crape Myrtles seem to sport every color in the rainbow.
Here I found the blurry view of our lawn through the stems of the Tall Tickseed to be an interesting composition.
