Each year, The Morton Arboretum’s trees are a prime stop for area leaf-peepers, as many of the Arboretum’s 4,200 varieties of trees turn a brilliant palette of vibrant reds, oranges and golds. Ed Hedborn is the Arboretum’s official Fall Color Scout and reports on the Arboretum’s color each week during the season.
