Early fall color can be seen near the Visitor Center.
September 30, 2019
Autumn is officially here and the trees are beginning to change color throughout the Arboretum grounds.
In The Morton Arboretum’s collections trees are still green with plants in more stressful sites beginning to show some early color. Plants in the Visitor Center parking lot medians, and some in full sun away from irrigated areas are turning earlier than those in the collections and natural areas. Hackberry (yellow), redbud (yellow), tree lilacs (yellow), and some Freeman maples (yellows and reds) are showing early fall color, more from stress than normal color change. The crabapple collections are beginning to show some fall fruit colors as well.
Woodland canopy trees are green, but black walnut and bur oak nuts will begin to drop. The ground layer has many late fall bloomers still blooming: fall asters and goldenrods are still blooming while white snakeroot is beginning to fade. The prairie is a good place to visit with gentians, asters, and other flowers blooming.
Colors will continue to develop, but the intensity and longevity is contingent on the weather ahead of us. Stay tuned!
