The Yellow Marsh Marigold is a native, perennial wildflower. It grows one to two feet tall. Its numerous round, green and yellow buds open into five to nine petal-like sepals that are up to 1-1/2 inches wide. The flowers are shiny yellow. It bears heart-shaped, basal leaves that are two to seven inches wide and has a thick, hollow, branching stem. It grows in shade or part shade in wet woods, marshy hollows, and stream edges. It likes muddy humus-rich soil. (EW)
