Explore our programs and projects to learn about how we are working to solve problems, create opportunities, and improve lives and livelihoods for Oregonians. Many of our programs also have national and global impact as they deliver knowledge and resources applicable to horticultural systems across the nation and around the world.

To ensure that we bring all the expertise we need to our research and extension programs, we often collaborate with other departments and disciplines at Oregon State University, with the farmers and growers who produce Oregon's food and nursery products, with landscape managers around the country, and with researchers around the globe.

Outreach and Extension

Oregon State's Extension Service serves Oregonians by conveying research-based knowledge that helps people improve their lives and communities. The Department of Horticulture assists in this mission by improving the environmental, economic, and social sustainability of integrated farm and food systems and ecological landscapes. Many of our faculty hold Extension appointments and are dedicated to sharing knowledge in our communities.
