Caltha Palustris "Plena" Marsh Marigold

This vigorous marginal aquatic perennial brings bold colour and structure to water gardens with its rounded, deep green foliage and spreading habit formed by creeping rhizomes. Growing up to 60 cm tall, it produces striking, fully double deep yellow flowers up to 8 cm across on upright, branched stems in spring, creating a bright and eye-catching display along pond edges or in consistently moist areas. Ideal for naturalizing in shallow water or damp soils, this hardy plant combines lush foliage with vibrant blooms, offering both ornamental appeal and reliable performance in aquatic or bog garden settings.
