Horticultural Research Institute

What Horticultural Research Institute does

The Horticultural Research Institute (HRI), founded in 1962 and headquartered in Columbus, Ohio, is a 501(c)(3) nonprofit research foundation that serves as the research and scholarship affiliate of AmericanHort, the leading U.S. trade association for the green industry. HRI directs industry-funded research toward practical challenges facing wholesale nursery and greenhouse growers, retail garden centers, landscape professionals, and the academic community. The organization is governed by a 23-member board of trustees and relies on a network of 70+ industry and academic volunteer reviewers to evaluate competitive grant applications. Its operating model is anchored by an endowment reported at over $19 million (as of 2022) and supported by charitable donations from individuals, horticultural businesses, and partner organizations across North America.

HRI's core deliverables span five product lines: (1) an annual Competitive Research Grants Program funding roughly 13–18 projects per year ($345.8K in 2020 rising to $564.5K across 18 projects in 2026, cumulative disbursements exceeding $11M); (2) the tHRIve Web Series, an on-demand platform distributing bite-sized research clips, researcher interviews, and live Q&A; (3) the SANC Risk Assessment Tool, a free web-based risk-assessment platform co-developed with the National Plant Board and USDA for nursery certification; (4) the HortCalculator, an online financial decision-support tool for ornamental growers analyzing profitability and ROI; and (5) the HRI Leadership Academy, a year-long intensive program developing next-generation industry leaders. Supporting initiatives include the Boxwood Blight Insight Group (BBIG), the Soilless Substrate Science (S3) collaboration, the Grow Wise Bee Smart pollinator program, the Million Pollinator Garden Challenge, scholarships, and the National Green Industry Survey conducted every five years since 1988. HRI does not sell products or services; all research outputs, tools, and best management practices are distributed at no cost.

HRI's revenue mechanics combine charitable donations, endowment investment returns, and leveraged government funding. It partners with USDA-ARS (administering the Floriculture & Nursery Research Initiative), USDA-NIFA (Hatch Multistate Research Fund), USDA-APHIS (Farm Bill Section 10007 pest programs), the National Plant Board, CABI, and 20+ land-grant universities to multiply industry dollars. Its primary research outputs are published through the peer-reviewed Journal of Environmental Horticulture (Allen Press/Meridian) and at the AmericanHort Cultivate conference. AI and machine learning appear only as topics of funded research (drone-based nursery inventory, consumer-engagement studies) rather than as core platform capabilities, and the organization operates with a 1–10 person staff.
