This is a pretty plant with dark foliage and scarlet flowers borne on tall spikes in late summer. It does well in pond edges with 10cm covering the crown in full sun to part shade. During very cold weather it would benefit from being moved to a cool greenhouse for the winter.
A creeping marginal with heart shaped green leaves and pretty bracts of pure white flowers June-July. It is suitable for bog gardens, stream and pond sides. It can be grown in 2-5cms of water over the crown in full sun or part shade.
