Sponsor-a-Tree Program

Fullerton Arboretum holds an extraordinary collection of trees from nearly every country in the world. The Fullerton Arboretum Sponsor-a-Tree Program supports the annual care of a select number of trees in the arboretum and our Level IV accreditation because healthy trees (particularly rare and threatened species) ensure offspring (germplasm) for tomorrow's plants.  Your tax-deductible gift will directly fund the care for a specific tree in the garden for a period of 1 year. Your gift will be recognized by a personalized sign placed near the tree.  Our Sponsor-a-Tree program is a meaningful way to honor a loved one, celebrate a milestone birthday, a special occasion or to show your love for your favorite Arboretum tree.  For trees in need of a sponsor and gift amount, please contact the Development Office at (657) 278-4798 or


Garden Benches

Honor a loved one or a special occasion by purchasing a garden bench including your personalized inscription on a brass plaque.  Throughout the arboretum, we have identified a limited number of locations that provide an ideal setting for distinctive wood benches where one can relax and enjoy the view.   Your tax-deductible gift of $10,000 provides important support for Fullerton Arboretum and places a bench in the garden for a fixed term of 10 years. For details on purchasing a garden bench, contact the Development Office at (657)278-4798 or

Planned Gifts — Planting the Seed of a Legacy

Charitable bequests and beneficiary designations are easy ways to “plant the seeds” of a future gift for the Arboretum. By designating the Arboretum as a beneficiary of a qualified retirement account or life insurance policy, you can provide a significant gift to the Arboretum.

There are several advantages to both bequests and beneficiary designation gifts:

  • Revocable — You can modify or revoke the gift at any time during your lifetime.
  • Avoid Probate — Bequests and beneficiary designations avoid the probate process.
  • Simple — Consult your estate attorney or simply fill out a brief beneficiary designation form provided by the plan or account administrator.

If you are interested in establishing your legacy and making a lasting impact at the Arboretum, please visit csufplannedgift.orgOpens in new window or contact our Office of Planned Giving at 657-278-3947 or

Plant Donations

We normally do not accept plant specimens as donations. If a plant is rare or unusual we may want to add it to our collections, but there is a high risk of disease transmission from foreign plants. Please contact our front desk at 657-278-3407 or to see if your plant would be a suitable addition to our collections.
