Caltha palustris, commonly known as marsh marigold 'Plena', is a vigorous marginal perennial with glossy, rounded green leaves forming dense clumps along pond edges and wet soils. In spring, it produces double, bright golden-yellow flowers that rise above the foliage, creating a showy and long-lasting display in wetland plantings.
This cultivar provides early nectar for pollinators and adds structure and visual impact to pond margins and bog gardens. Its spreading habit and bold, double flowers make it ideal for naturalistic water features and consistently damp areas.
