Fall color on the Arboretum's near west side.
October 13, 2017

Autumn color is developing this week at The Morton Arboretum, although is progress is relatively slow and subtle this year. Cool temperatures are slowing the progress of the color change. Despite recent rains, this fall has been very dry overall, and many plants are responding by turning color slowly with their leaves edged in brown.

Sugar maples in the East Woods are turning a yellow-orange with red highlights. Plants showing fall color now include sugar maple, ironwood, elm, black cherry, bitternut hickory, shagbark hickory, black walnut, redbud, Asian maples, tupelo, coffeetree, corktree, honey locust, katsura, zelkova, witch-hazel, gray and flowering dogwoods, tree lilac, and pawpaw. Crabapples and white-fruited mountain-ash are showing their fruits near Crabapple Lake.

The best areas to view fall color at the Arboretum this week are the Maple Collection (Parking Lots 7, 8, and 14); the Sumac Collection (Parking Lot 18); the Appalachian Collection (Parking Lot 16); the China Collection (Parking Lot 17); the East Woods (Parking Lots 8 through 13 and 15); the area around Lake Marmo (Parking Lots 27 and 28); and the Schulenberg Prairie (Parking Lot 25).
