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).[2]

Varieties

  • Poa poiformis var. poiformis (autonym)
  • Poa poiformis var. ramifer D.I.Morris – Trailing coast tussock-grass[6]

Var. ramifer is currently being studied to determine if it is synonymous with var. poiformis[7]
