Sabatia dodecandra, commonly known as Marsh Pink or Marsh Rose Gentian, is a perennial herb that is often evergreen in mild climates. It is native to wetlands such as marshes, wet savannahs, and the edges of ponds and streams in the Southeastern United States. This plant typically grows to a height of 0.5-2 feet (0.2-0.6 meters) and a width of 0.7-1 feet (0.2-0.3 meters). It features showy, star-shaped pink flowers with a yellow center that bloom in the summer, adding a splash of color to the garden.

Marsh Rose Gentian thrives in wet conditions and is suitable for water gardens, rain gardens, and naturalized areas. It is valued for its ornamental flowers and ability to attract pollinators such as butterflies. Gardeners should provide it with full sun and ensure the soil remains consistently moist to mimic its natural wetland habitat. While it prefers acidic soils, it can tolerate a range of soil types as long as they are wet. Care should be taken to avoid letting the soil dry out. Potential problems include root rot if drainage is insufficient and competition from more aggressive wetland species.CC BY-SA 4.0
