Which of the following is NOT a recommended ground cover for Louisiana?

Dianthus is not typically recommended as a ground cover for Louisiana due to its preference for well-drained, cooler climates and its susceptibility to the high humidity and heat that Louisiana experiences. This plant thrives better in conditions that provide it with partial shade and less moisture, which can sometimes be difficult to achieve in Louisiana's warm and humid environment.

In contrast, Ajuga, Pachysandra, and Creeping thyme are more suitable for ground cover in Louisiana. Ajuga is resilient and can adapt to various light conditions, making it versatile for different garden settings. Pachysandra is often used in shaded areas and thrives in the subtropical climate found in Louisiana, as it can tolerate moisture well. Creeping thyme is drought-resistant and thrives in sunny, well-drained areas, making it an excellent choice for Louisiana landscapes where heat and moisture levels can vary.
