Recent cool weather is leading to a slow emergence of fall color at the Arboretum. Some fall color is showing around Lake Marmo, tree tops in the east woods, and scattered color in the Maple and Appalachian collections, maples along Route 53, and in the Visitor Center parking lot.
Plants are slowly turning a mix of yellow, yellow-green, and green. Katsura, corktree, honey locust, hackberry, redbud, American elm, American and European beeches, Miyabe maple, bur oak and Kentucky coffeetree continue a slow turn to yellow and yellow-green. Flowering and gray dogwood are purple-red. Sumac, poison ivy, and Virginia creepers in full sun are red, while those in shady sites are still green. Yellow buckeyes are turning yellow. The Maple Collection and Lake Marmo are good places to take a fall color walk. Trees in our parking lot medians are showing the best color because of the more stressful site conditions.
Canopy sugar maples are turning orange-red in exposed areas. Ironwood, elms, hickories, and hackberries are slowly turning yellow. Sumacs at the Big Rock Visitor Station are turning red. The prairie is a good place to visit with late fall asters blooming, and tall grasses coloring.
The next two weeks may be the peak of our fall color, so come out and enjoy as often as possible.
