Garfield Park Conservatory

Described as “landscape art under glass” when it opened in 1908, the conservatory, while being one of the largest in the world, also boasts revolutionary architecture. With the building’s haystack shape and walls of stratified stonework, landscape architect Jens Jensen considered the Fern Room in particular, with its “prairie waterfall”—a stone and water element within a glass structure—to be one of his greatest achievements. About 120,000 plants representing some 600 species occupy the conservatory’s 1.6 acres, and four times a year flower shows premiere to herald the change in seasons.
