Cymbopogon schoenanthus (camel grass).
Cymbopogon schoenanthus is a perennial grass with fragrant foliage that is cultivated in tropical and subtropical regions for essential oil extracts from its leaves and roots, and for use as a culinary and medicinal herb. The species has rhizomes and densely tufted fibrous roots that tiller strongly, and has the potential to escape from cultivation. Once established, C. schoenanthus often behaves as a weed, forming monospecific stands. Currently It is only listed as invasive in Anguilla and included in the Global Compendium of Weeds.
