The landscape turns to red, orange, yellow and brown in the fall with turning of the leaves, but if you look down while out leaf peeping, you might spot some purple too like this aster.
There are over 120 species of the genus aster found in the United States and are primarily known for their fall flowering. The late blooming flower provide nectar for the butterflies, bees and other insects. In the winter, the heads provide seeds for tree sparrows, grouse, goldfinches and chipmunks. But then my chipmunks just eat out of the bird feeder.
