Marsh cress is a wetland plant that thrives in consistently moist to waterlogged soils, making it ideal for rain gardens, pond margins, or boggy areas. It tolerates partial shade but performs well in full sun as long as adequate moisture is maintained. This low-maintenance plant requires little care once established in a suitable wet environment.
