0-092 – Probably our largest Shingle Oak (Quercus imbricaria) here at Oak Ridge, this magnificent tree forms the background for the historic Garden Temple structure. It develops better fall color than many other shingle oaks and holds it foliage late into winter through a process called marcescence. The leaves are unique among central Illinois oaks because they have neither teeth nor lobes, and the acorns mature in two years.
