Overview

Mission

To preserve, share, and celebrate america's gardens and diverse gardening traditions for the education and inspiration of the public.

What it reported doing in 2025

Our organizational practices focus on three main areas: preservation, education, and advocacy. We work to restore historic american gardens, assist private gardens in their desire to become public amenities, present educational programs for all ages relating to the history and cultural significance of gardens and gardening, and open private gardens across the nation to the public through our "open days" program.continued on schedule o.in 2025, the garden conservancy continued to strengthen and expand its programs thanks to the generosity and engagement of a growing community of members, donors, and event participants. During the 2025 season, open days welcomed more than 32,000 visitors to 347 garden-visiting opportunities and presented sixteen virtual programs to over 7,000 participants. The national speaking tour featured celebrated photographer ngoc minh NGO, who shared her passion for roses and photography and her insights into breathtaking rose gardens from england and france to japan and the united states. Our garden futures grants program (including the page dickey grant for american gardens) supported twenty-eight non-profit organizations making a difference in their local communities through garden-based programming and the study of garden history. Our preservation program continued to offer guidance and assistance to those seeking resources to preserve or restore gardens; while also ensuring the longevity of the eight gardens the garden conservancy protects through conservation easements. Through the suzanne and frederic rheinstein fund for documentary films, we continued the film documentation of the anne spencer house and garden museum in lynchburg, va, and held a premiere of earth i thank you: the garden and legacy of anne spencer at the smithsonian's national museum of african american history and culture in Washington, dc.nancy friese became the garden conservancy's first artist in residence. Her residency focused on documenting the shifting seasons at two landmark sites currently under restoration: weathersfield estate & garden in amenia and blithewood garden in annandale-on-hudson.

  • Includes noncash contributions: Reported contributions include donated property or goods.

The verdict

SUPPORTED - A large share of available resources goes toward mission work and the filed numbers largely add up. The filing does not identify recipients for some grant dollars and fundraising costs are high for each dollar raised.
