Deschampsia antarctica (Antarctic hair grass) is one of two flowering plants native to Antarctica, the other being Colobanthus quitensis (Antarctic pearlwort).
They mainly occur on the South Orkney Islands, the South Shetland Islands, and along the western Antarctic Peninsula. A recent warming trend has increased germination, and thus number of seedlings and plants, also extending their range southward to cover larger areas; reports indicate a twenty-fivefold increase in their number.[1] This species extends south of 69 degrees south latitude.[2]
