From A Wiki of Ice and Fire
Green lands is the term mainly used by the ironborn to refer to the lands of Westeros that lie outside of the Iron Islands. The free folk north of the Wall have also been known to use the term green lands to refer to the Seven Kingdoms south of the Wall.
We shall sweep over the green lands with fire and sword, root out the seven gods of the septons and the white trees of the northmen ... —thoughts of Aeron Greyjoy
It made him sad to think that he would never see the green lands, the warm lands beyond the Wall that Mance used to sing about.—thoughts of Varamyr
