Help Us Grow

The iris gardens are funded by the non-profit organization The Citizens Committee of the Presby Memorial Iris Gardens. 

Each year The Citizens Committee depends on the generosity of contributors to raise its yearly operating budget of $200,000 to maintain this living botanic museum.

The Citizens Committee’s partnership with the historic Essex County Parks system benefits our work with publicity and joint efforts sponsoring year-round events.  However, the operation of the Presby Iris Gardens is not part of any local, county or state budget.

Your donation will help us continue our preservation and cataloging efforts for the iris and expand horticultural public education programs for the community. Donations are tax-deductible to the fullest extent allowed by law.
