The Spring Hill Ornamental Horticulture Substation (now the Ornamental Horticulture Research Center) can trace its beginnings to 1928 when an Alabama Agricultural Experiment Station entomologist was sent to Mobile to help Satsuma producers combat citrus pests. Work at the substation was gradually expanded to include azalea and camellia insects.

In 1945 Auburn severed its ties to the unit, but six years later in response to a severe freeze in 1950 and to grower needs, Alabama legislation funded restaffing of the field station.

Disease and insect control for ornamentals has been the major thrust for research at the station, but other aspects of nursery production have also been studied through the years.

At 18 acres, the OHRC is the smallest among the Alabama Ag Experiment Station’s outlying units. The substation was originally established on four acres near Mobile. In 1930 the city of Mobile deeded seven acres to Auburn University and in 1965 seven additional acres were deeded from Mobile to the station.
