Description
The Essex County Presby Memorial Iris Gardens is an internationally renowned garden that began with flower donations from the Presby family, American Iris Society, Kellogg Gardens, Joseph Van Vleck, and international admirers.
It is the largest public iris garden in the United States and is listed on both the State and National Registers of Historic Sites. Located at the base of Mountainside Park in Upper Montclair, the Gardens contain nearly 14,000 irises of around 3,000 varieties that produce more than 100,000 blooms each May.
It is a living museum of botanical preservation with some varieties dating back to the 1500’s. Locals lovingly refer to the Gardens as the "Rainbow on the Hill." While walking through the gardens, visitors will see every bed marked with a plaque summarizing the collection planted.
Additionally, each iris has a corresponding label marker with information unique to its identity. The 2012 bloom season marks the site's 85th Anniversary.
