Caltha palustris polypetala

Caltha palustris, commonly known as marsh marigold 'Polypetala', is a vigorous marginal perennial with glossy, rounded green leaves forming dense clumps along pond edges and wet soils. In spring, it produces semi-double to multi-petalled bright yellow flowers that rise above the foliage, offering a full and textured display in wetland plantings.

This cultivar supports early pollinators and provides shelter for small wildlife in pond margins and bog gardens. Its spreading habit and bold, textured flowers make it ideal for naturalistic water features and consistently damp areas.
