Reliable and long-lived perennial which provides attractive vertical accents to a planting. Sword like leaves encircle slender wiry stems. Simple pure white flowers open progressively up each stem to culminate in a fine airy show. Associates well with fine grasses like Stipa tenuissima in a gravel planting or with simple daisies like Anthemis 'Sauce Hollandaise' in the front of a border.

• Garden care: Selectively cut out old foliage to reveal attractive new growth. Dislikes a waterlogged soil. Divide congested plants in spring or autumn. Leave flower spikes to mature and form attractive seed heads which will self-seed if permitted.
