Ghost grass

"In the Shadow Lands beyond Asshai, they say there are fields of Ghost Grass, with stalks as pale as milk that glow in the night, murders all other grass. The Dothraki believe that one day, it'll cover everything, and that's the way the world will end."

―Ser Jorah Mormont

Ghost grass is a type of vegetation that exists on the continent of Essos. It is found in the Shadow Lands beyond Asshai. Ghost grass is pale in color and glows in the moonlight. It kills other types of grass.

History

Season 1

Ser Jorah Mormont tells Daenerys Targaryen that ghost grass is native to the Shadow Lands. The Dothraki believe that one day ghost grass will fill the entire world, killing all other types of vegetation, and that is how the world will end.

In the books

In the A Song of Ice and Fire novels, ghost grass is described similarly to the TV series. The map collection called Lands of Ice and Fire shows ghost grass growing in vast quantities all around the mountains of the Shadow Lands, extending down to Asshai and east along the shores of the Saffron Strait, as well as northwest towards the borders of Yi Ti.
