Marsh arrow-grass is a specialist wetland plant requiring permanently wet, boggy, or marsh-like conditions to thrive, making it unsuitable for typical garden settings. It is best used in ecological restoration projects, constructed wetlands, or naturalistic bog gardens where saturated soils can be maintained year-round. This plant demands consistent moisture management and is not recommended for casual home gardeners without dedicated water features.
