363 species of vascualar plants have been documented in the park. Because of the wide range of habitats some plants are found in many areas of the park while others are only found in small areas.
The park is home to some endangered plants and others that are of special concern in South Carolina.
Of the 363 documented plant species at least 15% of them are not ntoive. Many of these species were planted or are harmless componenets of the current flora that found their way into natural areas from plantings or errant seed mixes. However, at least 13 of the species are considered aggressive or potentially aggressive invasive species that are outcompeting and replacing native species. These species are probably one of the biggest single threats to the overall ecological health of the park. Some of the most prevelant invasive species found in the park are Japanese honeysuckle (Lonicera japonica), Chinese / European privet (Ligustrum vulgare / sinense), Japanese Stiltgrass (Microstegium vimineum), and Johnson grass (Sorghum halepense)
