Holden’s staff strives to develop and share a deeper understanding of horticulture, conservation, and environmental science. There are a wide variety of opportunities to learn more about plants, sustainable gardening practices, and tips from the experts to successfully incorporate a variety of plants into your home landscape.

The conservation of our natural resources is a key part of our mission with the Arboretum’s extensive natural areas being managed for the purpose of sustaining or increasing current levels of native biodiversity, with an emphasis on plants. Working with the Center for Plant Conservation, Holden Forests & Gardens horticulturists work to preserve endangered plant species, many of which can be found in the Myrtle S. Holden Wildflower Garden. The Arboretum’s collections included a number of tree species threatened with extinction. To learn more about the threats facing tree species around the globe, visit the Global Trees Campaign.
