Our History

The history of the Presby Memorial Iris Gardens is one that is deeply entrenched in the history of its community, Montclair, New Jersey.

The Gardens were started in 1927 as a memorial to Frank H. Presby, one of the founders of the American Iris Society and a leading citizen of Montclair. Frank Presby was an iris hybridizer and owned a fine iris collection. It was his expressed wish to give a collection of his favorite flower, the iris, to Montclair’s newly acquired Mountainside Park.
