The property contains a 19th-century historic home that predates the formal establishment of the botanical gardens.
The Black Creek floodplain provides a unique microclimate that allows mountain laurel to grow successfully at an elevation significantly lower than its typical mountain habitat.
The site acts as an outdoor laboratory for the biology department of the adjacent Coker University.
The gardens were once part of a plantation established in the early 1800s.
The boardwalks allow for the observation of wetland species that are typically inaccessible in the surrounding sandy terrain.
Kalmia Gardens is a 35-acre botanical site managed by Coker University, situated along the Black Creek floodplain in Hartsville, South Carolina. The grounds feature a 1930s-era historic home, the Thomas E. Hart House, surrounded by landscaped gardens and secondary-growth forest. A boardwalk system traverses the wetlands, providing access to diverse habitats including sandhills and acidic swamps. The gardens are particularly noted for their extensive collection of mountain laurel, known locally as kalmia, which flourishes in the region's unique soil conditions. Visitors can explore native plant displays, ornamental azaleas, and formal garden sections interspersed with natural woodland trails. The site serves as both an educational resource for botany students and a public recreation area. It remains one of the few places in the Pee Dee region where varied ecosystems transition closely together.

Bring insect repellent, as the boardwalks near the floodplain can attract mosquitoes.
Wear sturdy, closed-toe walking shoes as the woodland trails can be uneven or muddy after rain.
Check the official website for scheduled guided tours or special university events before your visit.
Do not attempt to walk off-path, as the swampy ground near the creek can be unstable and hidden from view.
The Thomas E. Hart House is typically closed to the public except for special events or pre-arranged tours; the gardens are closed on major holidays.
Stay on marked trails to protect the delicate wetland plant life; pets must be leashed.
