Galium antarcticum, Antarctic or subantarctic bedstraw, is a low perennial herb from the coffee family that forms weak, mat-like stems and grows in cool, damp ground. It is one of only two vascular plants native to Antarctica, so it is grown mainly by specialists and botanic gardens rather than as a garden or houseplant.

About

Galium antarcticum, commonly known as Antarctic bedstraw or subantarctic bedstraw, is a species of flowering plant in the coffee family. It has a largely subantarctic range.

Where it grows

It is found in southern South America in Chile and southern Argentina, as well in the Falklands and South Georgia and on the Crozet, Kerguelen and Macquarie Islands. It occurs on damp ground, often on the margins of lakes and streams. The species is listed as Critically Endangered in Australia, due to its very small population on the Australian territory of Macquarie Island.
