Marsh Marigold is an excellent choice for a water garden, a bog garden, along the verges of a pond or stream or to naturalize in low-lying areas. Marsh marigold is one of the first signs of spring with its bright yellow flowers in wet soils. The flowers look like oversized buttercups and the stems branch, and they are limp and hollow. Upper stem leaves are smaller and stalkless. Marsh Marigolds may be found growing just about anywhere there is water and sun.
