This perennial grass grows from a thick rhizome. It has stems up to 2.5 meters tall and 1 centimeter thick. It may grow erect or bent over. The thick, firm leaves are up to half a meter long.[2] They are bluish in color.[3] The inflorescence is a narrowed panicle up to 80 centimeters long by 17 wide.[2] Some seed is produced but most reproduction is vegetative, with new plants sprouting from tillers and the rhizome.[4]
This grass is commonly used for dune stabilization projects.[5] It is used to prevent erosion.[6] The aboveground plant parts act as a windbreak, preventing the sand from being blown away, and the large root system stabilizes the sand in place.[4] It can also be used in revegetation projects at other areas, such as mine spoils.[6] Specifically, var. amarulum is valuable for these projects. The roots grow six feet deep. The cultivar 'Atlantic' is available.[7]
A cultivar of P. amarum called 'Dewey Blue' is also used for ornamental purposes.[8]
