​K-State's Olathe Horticulture Center, in rural Johnson County, Kansas, (35230 West 135th Street, Olathe, KS 66061) is situated on the eastern side of land that was once the Sunflower Ammunition Plant.  The research center sits on 342 acres that includes 150 acres native woodland, 75 acres bottomland and 117 acres upland soil grassland. Spoon Creek runs through the site and provides irrigation water for research plots.  The center, which is a unit of K-State Research and Extension, supports five full-time employees, several graduate students in the Urban Food Systems Program and part-time summer student workers.

Our Vision: To be a regional resource and center of excellence in applied research and extension programs that serves the current and future needs of turfgrass, landscape, fruit, vegetable, and forestry industries as well as the local and regional economies they support.
