In July and August, whorls of tubular, lilac flowers appear at intervals like fluffy beads, on erect stems held high above large, downy leaves. Even after the flowers fade, this plant retains a dramatic presence in the border, with architectural seedheads that look wonderful among late-flowering perennials and grasses. This is a versatile, robust perennial that can cope with drought and is equally at home as part of a cottage garden scheme or among silver leaved plants and ornamental grasses.
