Juncus effusus ‘Spiralis’, commonly known as Corkscrew Rush, is a distinctive marginal pond plant valued for its unusual twisting, spiral green stems that create a unique architectural feature around ponds and water features.
The tightly curled stems grow in dense clumps and provide year-round interest, making this plant particularly popular for contemporary pond designs, patio ponds, and container water features. During summer, small brown flower clusters appear along the stems, adding subtle seasonal detail.
Juncus effusus ‘Spiralis’ grows well in shallow water or consistently damp soil and is ideal for planting in aquatic baskets along pond margins or in bog gardens. Its compact size makes it perfect for smaller ponds where a striking structural plant is desired.
