Our History
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.
