The roots of the Horticultural Research Institute go back to the 1950’s, when leaders of the American Association of Nurserymen established the “American Nurserymen’s Research Foundation” in 1954. The motivation was to fund research in industry business operations and marketing to supplement research being done on plants and production at land grant universities. The foundation bumped along for almost ten years. In 1962, a revamped Horticultural Research Institute replaced the older foundation. Eventually, two organizations were formed: Horticultural Research Institute the membership organization and several years later on July 7, 1975,  the 501(c)(3) Horticultural Research Institute Endowment Fund, the charitable foundation.

Over the lifespan of the two organizations, the Horticultural Research Institute Endowment Fund developed into a robust endowment fund that eclipsed the former Horticultural Research Institute in operational and fiscal capacity. As a result, it was determined that the needs of both organizations could be better served if the two were to merge into a single entity. On January 1, 2009, Horticultural Research Institute and Horticultural Research Institute Endowment Fund formally merged into the new Horticultural Research Institute. The new Horticultural Research Institute is an IRS-recognized 501(c)(3) tax-exempt research and educational foundation.

Horticultural Research Institute is the horticulture community’s research and development organization. 

HRI’s work strengthens and improves the horticulture community for the benefit of all industry segments—nursery growers and greenhouse growers, retail garden centers and landscape companies.

The extraordinary generosity of donors, both past and present, make it possible for HRI to develop and support research efforts aimed at invigorating and enhancing your community. These efforts result in advancements in pest management practices, increased mechanization/automation, and improvements in production efficiency—all of which impact your horticulture community, your business, and your legacy.

It is only with your support that HRI’s research and advocacy efforts are made possible. Your willingness to invest and contribute is what drives HRI’s success.
