GUN-ner-ah
Gunneraceae
These evergreen perennials are grown for their attractive foliage, which takes forms ranging from massive and clump-forming to diminutive and mat-forming. The former produce architectural leaves which form broad canopies and create stunning garden specimens.
Noteworthy characteristics:  Some produce large flower spikes that also garner interest. Most species originate from moist regions, and the large specimens look particularly at home at the water's edge.
Care:  Most prefer deep, moist soil, in sun or partial shade. Large species need shelter from drying winds.
Propagation: 

Sow seed when fresh and overwinter in a cool, frost free location; germination is slow. Take basal leaf cuttings and divide small species in spring.
