Caltha palustris
marsh marigold
Marsh marigold is notable for its bright yellow spring bloom and its high tolerance for shade. The glossy, deep green leaves look good all season long, and the early bloom can give wet spots and pondsides a spark of color in the spring when taller wetland species have barely begun to emerge.
