The Presby Memorial Iris Gardens is the world’s largest non-commercial garden dedicated to irises. Spread over 6.5 acres in a park-like setting on Upper Mountain Avenue in Montclair, the unique gardens are open to the public without charge.

Established in 1927 to honor noted horticulturist Frank Presby, the gardens feature a world-class collection of over 10,000 individual plants representing 6 species and over 3,000 different named varieties of irises.

The Walther House, an excellent example of Victorian architecture, sits adjacent to the gardens, which are also home to a museum shop and the headquarters of the Citizens Committee that oversees the gardens.
