Small egg-shaped claret-coloured flowerheads appear like drumsticks on tall slender stems above strap-like mid-green leaves in mid- to late summer. Planted en masse in a border in full sun these diminutive claret flowers look great emerging from a screen of foliage or against a backdrop of ornamental grasses. They gently fade as summer comes to a close.
