Marsh willowherb is a moisture-loving perennial best suited to boggy garden edges, pond margins, or consistently wet soils. Water frequently to prevent the soil from drying out and place in a sunny to partly shaded location. It requires moderate care to keep it thriving in non-wetland garden settings.
