A dramatic, architectural plant, with massive, deeply veined, rounded leaves held on stout, prickly stems. This majestic plant looks wonderful at the edge of a large pond or stream where its foliage is reflected in the water. One of the most spectacular plants that can be grown in Britain, it requires deep, permanently moist, humus-rich soil, lots of space and protection from cold, drying winds.
- Garden care: Cut back the dying leaves in autumn. In frost-prone areas protect the crown of the plant with a dry winter mulch such as straw.
“Give it pride of place in a large border or damp woodland, with lots of humus (an a hose pipe near by); ideal by a pond, stream and ditch”
