These plants are low maintenance and do not require fertilization after establishment, however they do appreciate bone meal just after planting. They thrive in moist, acidic soil with ample humus. Due to their robust rhizomes, they are particularly useful for erosion control. You can plant these with a native wetland perennial mix to further attract pollinators to your garden!
