A graceful, hazy plant with airy wands of white, star-shaped flowers from May to September. This exceptionally long-flowering perennial, with slender, grey-green leaves, looks equally at home in an informal cottage-style garden or among soft grasses in a perennial border. A major attraction to butterflies, it continues to flower through the first hard frosts of autumn into winter

Grow in well-drained, fertile, moist soil is preferable, but will tolerate drought and partial shade. Remove spent flowers to prolong flowering period. Close planting or support from neighboring perennials is beneficial. May be cut back by half in late spring to control size. May be divided in spring.
