Galium antarcticum, commonly known as Antarctic bedstraw, is a perennial herb native to the cool temperate regions of southern South America, including Chile, southern Argentina, the Falklands, South Georgia, and several subantarctic islands. It typically grows up to 2 inches tall in damp ground, often found in moist meadows, bogs, and along the margins of lakes and streams where it forms low, dense mats. Antarctic bedstraw is adapted to cold, wet environments and is a component of the unique subantarctic flora.

Antarctic bedstraw is characterized by its prostrate stems, small, lanceolate leaves, and solitary pinkish-buff flowers that bloom in January. The fruits, which are small and dry, mature in February. While not commonly cultivated, it can be of interest to botanical gardens specializing in rare or endangered species. In cultivation, it would require consistently moist soil and cool conditions to thrive. It is critically endangered in Australia due to its small population on Macquarie Island, highlighting the importance of conservation efforts.CC BY-SA 4.0
