The etymological root of the binomial name Schoenoplectus is derived from the Greek schoinos meaning ‘rush’ and plektos meaning ‘twisted’. Lacustris is derived from the Latin lacus meaning ‘lake’.

The landscape architect may find Schoenoplectus lacustris useful for UK native wetland planting schemes, at the edges of lakes, ponds or slow moving rivers.

Ecologically, Schoenoplectus lacustris is valuable along fresh water shorelines helping to buffer against water erosion.

Schoenoplectus lacustris prefers wet, poorly drained, fertile soils. It tolerates most pH of soil. It will tolerate a water depth to 30cm.

Schoenoplectus lacustris requires little maintenance.
