Tall, graceful and elegant, the species from the United States. They are a short-lived plant (about four to five years) but look gorgeous in a woodland garden and are easy from seed.
Pale yellow flowers up to 80cm (32in) from June to July and growing 45cm (18in) wide. Happy in most good garden soils in sun or light shade.
