Fall Color Report: October 18 - 24, 2019

A close look at yellow leaves
Brilliant fall color has arrived at the Arboretum
October 17, 2019
Leaf color is becoming more apparent in The Morton Arboretum’s tree collections and woodlands. Open areas show more red and orange, while more shaded trees in the woodlands are mostly yellow. Sugar maples at Lake Marmo and near Big Rock Visitor Station are turning yellow and orange-yellow. The natural areas’ woodlands, where sugar maples predominate, are mainly yellow-green, and a sprinkling of leaves have already dropped to the ground.The gardens, the Visitor Center area, and the tree collections are also showing yellows and yellow-greens. 
 
In general, leaf color develops faster and is often more vivid on trees and shrubs that are planted in more stressful sites. For that reason, plants in the visitor center parking lot and entrance drives are showing nice fall color. Among them are hackberry  (yellow), redbud (yellow), tree lilac (yellow), coffeetree (yellow), some Freeman maples (yellows and reds), and sumacs (reds). The crabapple tree collections on the east and west sides have many red fruits.  Yellow color can be found on many trees in the tree collections, including linden, redbud, hickory, walnut, bur oak, Miyabe maple hackberry, and catalpa. 
 
This week, more colors should develop.  The cool, sunny days that are in the weather forecast should accelerate the change. Come at different times of the day to enjoy colors that change with the angle of the sun, and visit often to watch colors develop on your favorite plants and collections.
