Cymbopogon nardus has been cultivated in the United States, but the variety involved is not known. Cymbopogon nardus (L.) Rendle var. nardus, which is native to Sri Lanka, is the common citronella grass. It differs from C. nardus var. confertiflorus (Steud.) Stapf ex Bor, which is native to both Indian and Sri Lanka, in having unawned spikelets and 2n = 20, rather than awned spikelets and 2n = 40, 60. Both varieties have been widely introduced beyond their native range.
