Plant details

This is a fascinating species with large, bell-shaped, off-white flowers, flushed green and purple, hanging down from drooping stalks at the top of stout stems but, after pollination, stand erect. Perfect for flower arrangers, particularly those who enjoy dried flowers, with the dried seedheads adding interest to a display. Frost hardy, these plants require a sunny and partially shaded site and can be grown in rough grass or borders in any moderately fertile soil that is neither too dry nor waterlogged. They can be propagated by freely produced offsets in late summer or by seed in autumn.
