A colony of blooming marsh marigolds is a sight to behold at a time of year when most other plants are just emerging, and brown twigs and brown muddy patches are everywhere.
Marsh marigold is a mound-forming plant with glossy, heart-shaped leaves and large, showy, buttercup-like yellow flowers. Despite the common name, C. palustris neither looks like nor is related to marigolds. It is rhizomatous, and may seed in to form a dense groundcover in a consistently moist site.
Tolerates periods of drought, but will go dormant, losing all leaves.
