Note:  This listing applies to fertile varieties of vetiver grass, Chrysopogon zizinoides.  Fertile varieties should not be planted as they may produce seed and are potentially invasive.  Only sterile cultivars such as 'Sunshine' (USA) or 'Monto' (Australia) should be used for plantings on Pacific islands.

The listings below do not differentiate between plantings of sterile cultivars or fertile varieties unless specified in the literature.


"Perennial, the culms stout, up to 3 m high; leaf blades narrow, glabrous, 30-90 cm long, 5-12 mm broad, tapering at length to a fine point, the margins scabrous; panicle usually contracted, 22-37 cm long, the branches whorled, fragile, jointed, ascending, appressed, 5-7.5 cm long; spikelets paired, about 4 mm long, similar, one sessile, one stalked, falling entire at maturity, 2-flowered, the upper floret of sessile spikelet alone perfect, the others either female or sterile, the glumes with minute, prickly, wart-like projections, the glume of stalked spikelet almost smooth"  (Smith, 1979; p. 377).

Description from GrassBase. In Fiji, "cultivated in gardens but is also escaped and naturalized, occurring along roadsides and contour lines. ...it may be considered a roadside weed" (Smith, 1979; p. 377). In New Caledonia, "largement dispersé à présent, surtout en bords de routes" (MacKee, 1994; p. 63). Seed "Southeastern Asia to tropical Africa" (Smith, 1979; p. 377).
