Softstem Bulrush

Description

Schoenoplectus lacustris is a vigorous rhizomatous marginal aquatic perennial valued for its tall, clean vertical stems and natural wetland character. It grows at the edges of ponds, lakes, and slow-moving waterways, where it forms bold clumps and colonies that add height, structure, and habitat value to larger water gardens. This species thrives in full sun in reliably wet soil or shallow standing water. RHS recommends planting it in fertile wet ground or in water up to 30 cm deep, while Missouri Botanical Garden notes it is suitable for submerged containers, pond margins, stream edges, and bog gardens. Because of its vigorous root system and strong spread, it is best suited to large naturalistic ponds rather than small lined ponds. In the right setting, it creates an excellent vertical accent and supports a more ecological, wildlife-friendly planting style.
