Rare and beautiful plant. Height To 1.2 metres. Upright clump forming and somewhat bushy. Masses of slender 5-petalled star-like white flowers held in loose corymbs on wiry, branching, distinctively red stems in late spring to early summer. Moist, humus rich soil - quite drought tolerant once established. Lovely as a background plant for part shade. Foliage is an attractive red colour in autumn. A lovey rare, specimen plant. Winter dormant.
