We remember one of the most fantastic views we had of plants was the vast field of Gunnera at one of the large Cornish Garden Estates. Gunnera Manicata has enormous foliage and works well in very moist conditions even in the pond! If you want to create a massive display of large leaves this is the plant...
It is not always a hardy plant and should be lifted to protect from severe winters and kept dry.
