A tall, very showy perennial wildflower with large umbels of pink and mauve blossoms. This butterfly haven will naturalize freely, and produce attractive seed pods for use in dried flower arrangements. Named the “Swamp Milkweed” from its preference for a wetland habitat, but will also thrive in average garden soil. A favorite for butterfly gardens, and easy to grow!
