Applicants must submit an LOI prior to submitting a full proposal. The Trust supports projects that directly further research or education in ornamental horticulture in North America, South America, Central America, the Caribbean, Australia, and New Zealand.

The Stanley Smith Horticultural Trust supports education and research in ornamental horticulture through grants to botanical gardens, arboreta, universities, and other charitable organizations strongly-aligned with its funding interests.

The Trust awards grants for distinct projects, equipment and capital needs, and, under some circumstances for general operating support and salaries.

Funding Interests - The Trust seeks to fund projects that will further ornamental horticulture through organizations pursuing the following activities:

  • Research: The advancement of research in ornamental horticulture and the publication of the results of such research.
  • Public Gardens: Assisting in the creation, development, preservation, and maintenance of gardens accessible to the public for educational purposes.
  • Ornamental Plants: Promotion of the environmentally responsible introduction, cultivation, and distribution of plants which have ornamental horticultural value.
  • Publications: Assisting in the publication of books or other works relating to ornamental horticulture.
  • Education: Informal and/or formal educational activities that further ornamental horticulture.

In response to the COVID-19 pandemic, in 2020 and 2021, the Trust considered requests for general operating support from organizations whose activities normally are well-aligned with the Trust’s interests. This policy has been extended through the 2023 application cycle. The Trust recognizes the hardships gardens and other horticultural organizations experience due to damages caused by natural disasters (storms, fires, earthquakes, flooding, etc.), and welcomes requests from qualified organizations to support damage remediation.
