To support the Desert Botanical Garden's mission of conserving and promoting the desert plants and ecosystems through research, education, exhibitions, and community engagement.
Desert Botanical Garden Foundation’s largest recent grants are annual general support awards to Desert Botanical Garden Inc. in Phoenix, including $731,418 in 2025, $731,239 in 2024, and $713,864 in 2023. That pattern shows a foundation centered on sustaining the Garden’s core work rather than distributing funds across many outside organizations. Its stated mission is to support the Desert Botanical Garden’s conservation of desert plants and ecosystems through research, education, exhibitions, and community engagement. The foundation’s active programs reinforce that mission through endowment contributions that support general operating needs and mission-driven activities, a Huizingh Desert Research Fellowship for PhD training in desert research, and donation requests that provide complimentary memberships or guest passes to Arizona-based nonprofits for events. Corporate sponsorship opportunities also connect outside supporters to the Garden through tiered giving. Across these channels, the foundation supports plant conservation, botanical research, horticulture, environmental education, community outreach, and public programs with a clear emphasis on the Garden itself and its Arizona setting.
The foundation supports desert plant conservation and research through both operating support and training. In 2025, it gave $731,418 to Desert Botanical Garden Inc. for general support, and its Huizingh Desert Research Fellowship was established in 2011 to expand graduate training in partnership with Arizona State University. Education and public programming are also part of the funding mix. The endowment contribution program authorizes annual support for the Garden’s education, research, conservation, and public programming needs. Community outreach appears in smaller in-kind support as well: donation requests provide complimentary Friends & Family memberships or guest passes to Arizona-based nonprofits for events. Corporate sponsorship opportunities add another layer, with tiered options that support conservation, sustainability, arts and culture, and community engagement.
Recent grants cluster tightly around one size band: the 25th percentile is $722,552, the median is $731,239, and the 75th percentile is $731,328. The recent record also shows a recurring annual pattern, with general-support awards appearing in 2023, 2024, and 2025. This is a foundation that primarily channels resources through its own Garden-related structures, including endowment contributions and mission support, rather than a broad external grant portfolio. It also accepts unsolicited requests for some offerings, including donation requests and corporate sponsorship opportunities.
