Silver Leaf Stewards

The Silver Leaf Stewards program is the perfect way to honor family members or pay tribute to someone who has touched your life in a significant way. With your tax-deductible gift, a metal leaf plaque will be installed on a rock wall in the arboretum engraved with your honoree’s name.

Plant and Tree Collection

Gifts to the collections fund help to purchase or support Hoyt Arboretum's trees and plants, new plants, mulch and other care supplies, trail maintenance, volunteer resources, the plant inventory public database, gardening equipment, and capital projects.


Gifts to education support the ongoing education programs of Hoyt Arboretum Friends. Education programs provide a variety of services to the community including 30,000 maps annually, interpretive signage, guided tours, kid's tours, classes and presentations, the plant reference library, plant identification labels, collection and tour brochures, the arboretum website, newsletters, the Tree Buddies program, community outreach and the Hoyt Arboretum Visitor Center.


Endowment funds serve to provide resources for general operations or specific programs in perpetuity and are an important source of annual funding. Our endowment fund is managed through Oregon Community Foundation.

Commemorative gifts can be made payable to Hoyt Arboretum Friends and are tax-deductible as allowed by law.
