We do use that species all the time, and have a local source for plants and seed, but the landowner wants to use vetiver grass and we are concerned that it could be come invasive.

Good Morning 

Why don't you use Beardless Wild Rye ( Elymus triticoides) ?

--It's native to your area.
--Has been used successfully in restoration. 
--Is a good ribizomus grass and therefore a better competitor against invasives then bunch grass. --Does well in wetter situations like along a drainage ditch.
--Should be perennial in you area.
--Stays green all summer with a little extra water. Thus is can look nicer and is more resistant to burning 
--Self seeds successfully.
--Is known as a good native forage for cattle,  so could be great for wildlife.
--You can get it from the government as a specially bred species that is already approved for restoration work. (Sorry, but I forget who has it)
--Thus,  I imagine you might be able to get seeds in quantity for a good price. 

Let me know, if this helps.

HI All,

One of our partners in Yolo County is excited about using "vetiver grass" for bank stabilization along an irrigation ditch.

From Google:

Chrysopogon zizanioides, commonly known as vetiver is a perennial bunchgrass of the family Poaceae, native to India. Vetiver is most closely related to Sorghum but shares many morphological characteristics with other fragrant grasses, such as lemongrass, citronella, and palmarosa.

Vetiver (Vetiveria zizanoides) is a densely tufted, perennial clump grass with stiff leaf bases which overlap. It forms narrow, dense hedges when planted along the contours of sloping land, slowing down run-off and helping the water soak into the soil rather than washing off the slope.


 
Does anyone know if this grass is invasive (not-native, fast growing...looks suspicious to me)?  Of course we would like the landowner to plant native bunch grasses instead and are gathering info for our case.

Thank you!
