Marsh Marigold (Caltha palustris) is a seasonal interest plant with yellow flowers in early spring. They prefer wet soil in sun to part sun where they can grow up to 2 feet tall. They are a good choice for basins where there is consistent moisture. Companion plants include White Turtlehead (Chelone glabra) and Southern Blue Flag Iris (Iris virginica var. shrevei).
Maintenance
