Poa cita or silver tussock is endemic to the North, South and Stewart Islands, and is common in lowland to montane areas from sea-level to 1400m asl. It is found on stabilised coastal sands, river-beds, plains and hilly country, and is a conspicuous feature in the drier areas of both main islands, and Stewart Island as well, and is a principal constituent of lowland tussock grassland. This densely tufted tussock has a graceful habit, and grows to about 50cm tall, although more robust forms can reach 90cm. Depending on the form, it can range from light tawny yellow to a tawny colour that is toned down by the number of green leaves per tussock. It is a variable species, and some forms are smaller with finer foliage, while more robust forms have coaser leaves.For best results it is best grown in rather poor and dryish soils in an open sunny position. If treated too well and grown in soils that are constantly moist, it will grow out of character and lose its attractive form. Locally it is the main species of tussock on the Port Hills surrounding Christchurch.
