These gardens, in Wheaton, IL, are part of Cantigny, which was the estate of Col. Robert R. McCormick, former editor and publisher of the Chicago Tribune. Cantigny contains gardens, two golf courses, and the 1st Division military museum.
McCormick commanded the 1st Division's 1st Battalion, 5th Field Artillery at Cantigny (France), site od America's first victory in WWI. Cantigny is not taxpayer supported in any way, yet admission is free, with a charge only for parking.
The gardens are heavy on mass annual plantings, and they are a popular wedding site.
