Kalmia Gardens (30 acres) is a mature botanical garden located at 1624 West Carolina Avenue, Hartsville, South Carolina. Part of Coker College, it is open daily without admission. The gardens were established in the early 1930s by Mrs. David R. Coker on the land, which had become a neglected dump. Mrs. Coker made trails, dug a pond, and planted ornamental species including azaleas, camellias, tea olives (Osmanthus fragrans), and wisteria. In 1935 she opened the gardens to the public, and in 1965 she gave them to Coker College. The centerpiece of the gardens is the Thomas Hart House, built in the 1820s, and the home of the town's founder. It and the gardens are on the National Register of Historic Places.
