Strategic Grantmaking

Through strategic grantmaking, Horticultural Research Institute invests in a broad range of highly effective research projects. We invite researchers to explore the competitive grant opportunities made possible by our generous donors.

Since 1962, the Horticultural Research Institute has directed over $7 million of industry funds to research projects covering the full range of production, environmental, and business issues important to the horticultural trade.

Horticultural Research Institute only funds research that specifically deals with green industry-related issues. HRI-supported projects focus on significant problems, regulatory issues, and emerging opportunities in the nursery, greenhouse, retail, and landscape industry. HRI research focuses on the propagation, production, distribution, marketing, and sale of plant material.

HRI research strategically focuses on

  • Quantifying Plant Benefits
  • Gathering Consumer Insights
  • Creating Innovative Solutions
  • Producing Practical & Actionable Solutions

HRI seeks to support research that

  • has defined outcomes
  • creates applicable advice for businesses
  • represents a return on investment for the green industry

Grants are typically between $5,000 and $35,000, although larger awards have been issued. We encourage you to review our research priorities and project requirements and review process before applying for a research grant.
