This cultivated variety of the native \u003cem\u003eCaltha palustris\u003c\/em\u003e offers an even more ornamental appeal with its lush, multi-layered blooms.\u003c\/p\u003e\n\u003cp\u003eThe plant grows to a height of 30–60 cm (12–24 inches) and forms a dense clump of glossy, heart-shaped, deep green leaves. The foliage emerges early in the growing season and provides an attractive backdrop for the plant's dramatic floral display.\u003c\/p\u003e\n\u003cp\u003eIn spring, \u003cem\u003eCaltha palustris 'Plena'\u003c\/em\u003e produces an abundance of fully double, buttercup-like flowers, measuring 2.5–4 cm (1–1.5 inches) across. The flowers have numerous overlapping golden-yellow sepals, giving them a fuller and more textured appearance compared to the single-flowered species. These blooms are sterile, which means the plant focuses its energy on prolonged flowering rather than seed production, resulting in a long-lasting display.\u003c\/p\u003e\n\u003cp\u003eThis variety thrives in full sun to partial shade and prefers consistently wet, waterlogged soil, making it ideal for planting along the edges of ponds, streams, or in bog gardens. It can also tolerate shallow water depths of up to 15 cm (6 inches), making it suitable for aquatic planting schemes. Hardy in UK conditions, \u003cem\u003eCaltha palustris 'Plena'\u003c\/em\u003e is frost-resistant and thrives in a variety of soil types, including clay and loam.\u003c\/p\u003e\n\u003cp\u003ePropagation is typically achieved by division in spring or autumn, as the sterile flowers prevent seed production. The plant is low-maintenance and requires minimal care beyond occasional thinning to prevent overcrowding.\u003c\/p\u003e\n\u003cp\u003eIn addition to its ornamental qualities, \u003cem\u003eCaltha palustris 'Plena'\u003c\/em\u003e provides habitat and shelter for aquatic wildlife. Its dense growth helps stabilise soil along water margins, reducing erosion, while its early-season blooms add a burst of colour to the landscape.\u003c\/p\u003e\n\u003cp\u003eWith its exquisite flowers and glossy foliage, \u003cem\u003eCaltha palustris 'Plena'\u003c\/em\u003e is a show-stopping choice for water gardens, bringing a touch of elegance and brightening wetland settings with its cheerful and long-lasting floral display.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eWhy Choose Caltha palustris 'Plena' (Double Marsh Marigold)?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCaltha palustris 'Plena'\u003c\/strong\u003e, commonly known as \u003cstrong\u003eDouble Marsh Marigold\u003c\/strong\u003e, is an extraordinary aquatic plant that stands out with its fully double, golden-yellow flowers.
