Poa poiformis, commonly known as coast tussock-grass or blue tussock-grass, is a densely tufted, erect, perennial tussock grass, with distinctive blue-green leaves, that grows to about 1 m in height.

Its inflorescences are arranged in a dense panicle up to 30 cm long.

It is native to coastal southern Australia where it occurs along ocean foreshores, estuaries, dunes and cliffs.

[5][6] P. poiformis is also found on Kangaroo Island (South Australia) and Lord Howe Island (New South Wales).

ramifer is currently being studied to determine if it is synonymous with var.
