An eye-catching deciduous grass that produces fluffy, dark silvery-purple flower heads in late summer. The bottlebrush flowers are borne above an arching mound of slender green foliage that makes fabulous ground cover when planted en masse. Pennisetum alopecuroides 'Black Beauty' is a gently swaying grass that brings texture and movement to borders and delivers superb late summer interest. Height and spread: 100cm (39").
