(AP) With the arrival of autumn, the Morton Arboretum's official fall foliage color scout has begun his weekly updates.
In his latest dispatch, Ed Hedborn says warm, sunny days and cool nights during the first week of October have helped start the color change season at the arboretum in Lisle.
Getting to the details, he says the leaves of hackberries and redbuds are beginning to turn yellow.
Sumacs, poison-ivy and Virginia creeper vines in sunny locations are turning scarlet.
In woodland areas, he says, late fall-blooming asters still have shades of white and blue.
