Colobanthus quitensis, also known as the Antarctic pearlwort, is one of two native flowering plants found in the Antarctic region, the other being Antarctic hair grass. It has yellow flowers and grows about 5 centimetres (2 inches) tall, giving it a moss-like appearance. Due to climate change, the species has been spreading rapidly, particularly to areas outside Antarctica.
