Identification:
Fountain grass is currently only known to grow in a few locations in Maui County (see Maui map and Molokai map). Fountain grass is a perennial, clumping grass that can grow in a variety of habitats, from bare lava, to rangeland, to urban roadsides in drier areas of the Hawaiian islands (<127 cm rain/yr). It can reach a height of 0.2-1 m (0.5-3 ft) with bristly, cylindrical shaped purple or rose-colored flower head (100-250 mm or 4-10 in long).
