Coarse, bold-growing, and ornamental Chilian plants with immense Rhubarblike leaves, often 6-9 ft. across. The small flowers are borne on large erect club-like spikes in the centre of the plant. The plants are quite hardy in most places, and flourish on the banks of lakes, ponds, streams, etc. The best kinds are manicata and scabra, otherwise known as chilensis. They are propagated by division or seeds in spring. Trade very limited.
