Caltha palustris alba (White marigold)

Caltha palustris, commonly known as marsh marigold 'Alba', is a robust marginal perennial with rounded, glossy green leaves forming dense clumps along pond edges and wet ground. In spring, it produces bright white, buttercup-like flowers that stand above the foliage, offering a striking, elegant contrast in wetland plantings.

This cultivar provides early nectar for pollinators and contributes to wildlife-friendly planting in bog gardens and pond margins. Its spreading habit and bold flowers make it ideal for naturalistic water gardens and consistently wet sites.
