Marsh lousewort is a specialist wetland plant that requires permanently moist to wet, nutrient-poor soil and is best suited to bog gardens, pond margins, or wet meadows. It is hemi-parasitic on the roots of neighboring grasses, so it must be planted alongside suitable host plants to thrive. This plant is not recommended for typical garden beds and is best left to experienced growers with the right habitat conditions.
