Description:

Marsh Marigold is a mounded, succulent perennial with large, showy, bright yellow flowers, which bloom April-June. The common name is misleading, since the flowers resemble buttercups rather than marigolds. The glossy leaves are described as having a heart or kidney shape. When ripe, the seed pods split open to disperse the seeds. As the common name suggests, this plant prefers wet, boggy soils. Use it in rain gardens, bog gardens, or shallow water margins of ponds and water gardens.
