Abrotanella forsteroides

Abrotanella forsteroides, commonly known as the Tasmanian cushion plant, is an angiosperm endemic to Tasmania, Australia. The plant is a dicot species in the daisy family Asteraceae and can be identified by its bright green and compact cushion like appearance. The term cushion plant refers to a characteristic growth habit adopted by a variety of species and families growing in alpine and subalpine environments. The growth habit is an adaptation to low nutrient areas and typically involves deep tap roots and densely-packed stems, which decay to form a layer of peat under the plants. This dense growth pattern provides insulating properties to the plant, preventing root exposure to sub-zero temperatures, and forms a mat- or cushion-like structure. ...read more on Wikipedia.
