Welcome to The Department of Horticulture and Landscape Architecture. We strive to provide expert instruction and guidance to our students in a warm and friendly environment.

OSU’s Horticulture and Landscape Architecture Department embraces the teaching, research, and extension triad of our land grant university mission. Dedicated to excellence, faculty and students explore all aspects of horticulture and landscape architecture including plant breeding, food crop production, athletic turf management, urban landscaping and sustainable design. With research locations throughout the state, students have the opportunity to study plant production with a range of environmental variabilities. Our department works hard to maintain close ties with graduates who now work in the industry nation-wide, often leading to networking opportunities for current students.  Approximately $100,000 in scholarships is awarded annually by the department to horticulture and landscape architecture students.


The OSU Department of Horticulture and Landscape Architecture offers three undergraduate majors: horticulture, landscape management and landscape architecture. The horticulture degree has four options including turf management, horticulture science, horticulture business and public horticulture. The department also offer a Master’s in Horticulture and has associated Ph.D. opportunities.

Students receives one-on-one academic advising from departmental faculty to ensure a successful experience. With hands-on labs in construction, landscape design, plant identification and other courses, students learn by doing in a safe, controlled environments where they are encouraged to ask questions and engage in discussion. Student have the opportunity to travel in-state with class field trips and compete in national student industry competitions. Often these interactions lead to hiring opportunities upon graduation. There are several study abroad opportunities for students to understand the impact horticulture has around the world.


Committed to advancing sustainable horticulture practices, faculty and students work to identify ways for plant production to be more efficient. Our world-class turfgrass research program has developed grass for stadiums around the globe and is selecting for drought resistant, cold hardy grass. Post-harvest research looks at extracting oils to improve value to horticulture commodities and mechanisms involved in shelf life extension of horticultural products. Departmental research also extends into urban and greenhouse management with hydroponics and LED greenhouse lighting.


The Oklahoma Cooperative Extension Service (OCES) is a network of specialist throughout the state, working with citizens to bring them researched-based information to help solve their local problems. One of our keynote extension programs is our “Oklahoma Gardening” television show that airs weekly on OETA showing step-by-step gardening instruction. Extension specialist also work with industry producers and provide regular educational training through the Farm to Market, Grape and Pecan courses. The Master Gardener Program and our Youth Program extend educational training to communities across Oklahoma.
