Marsh Marigold - Caltha palustris

Marsh Marigold

The bright yellow blooms of the marsh marigold can be found throughout Ohio, primarily in swamps and wet meadows. Marsh marigold (Caltha palustris) is one of the earliest and showiest of wetland plants--it can be seen from mid-March to late April. It is a member of the buttercup family and its generic name is derived from the Greek calathos, meaning a cup or goblet, which refers to the shape of its flowers. The plant’s flowers open and close with the rising and setting of the sun. The English name, marigold, refers to its use in church festivals in the Middle Ages. Often growing in large tufts, marsh marigold can be seen state nature preserves with swamp forest habitat, such as Lawrence Woods in Hardin County and Cedar Bog in Champaign County.
