What is Vetiver Grass?

Vetiver, Vetiveria zizanioides, (recently reclassified as Chrysopogon zizanioides), is a type of grass with very unique characteristics that is effectively used in soil/slope stabilization, flood control, land slide stabilization, land rehabilitation, as well as many other applications. It forms a dense clump of shoots above the surface and grows a thick and seemingly impenetrable web of roots that delves 13 feet (4 meters) straight into the ground. The roots essentially form a wall of steel that prevents erosion-prone slopes from slipping away while the thick hedge that grows above ground controls sediment flows. This provides excellent protection against soil deterioration. Vetiver is an extremely hardy plant that can be used in most climates, but yields fastest root growth in areas such as the Southern and Southwestern states, and California that have a Mediterranean type climate where there are hot summers and temperate winters.

Advantageous Characteristics

• Unique, dense root systems grow straight down, with little to no outward deviation. The effectiveness of such a system has won Vetiver the nickname "The Soil Nail."
• The species of Chrysopogon zizanioides, that is promoted in nearly 100 countries for Vetiver System applications originates in south India, is sterile and non invasive.
• Though ideal conditions can support rooting depth reaching 3-4m in the first year, average rooting depths of 2-3m are not uncommon in the first year.
• Vetiver grows clumps of stiff, erect stems that can stand up to relatively deep water flows - See Photo 1. A dense hedge is formed when planted close together acting as a very effective sediment filter and water spreader.
• Vetiver is highly resistant to pests, diseases and fire - See Photos 2, 3. Susceptibility to pests, if at all, may occur when the plant experiences unfavorable environmental conditions such as drought.
• New shoots develop from the underground crown making vetiver resistant to fire, frosts, and trampling.
• New roots grow from nodes when buried by trapped sediment. Vetiver will continue to grow up with the deposited silt eventually forming terraces, if trapped sediment is not removed.
• Another less obvious characteristic that sets it apart from other tree roots is its power of penetration. Its strength and vigor enable it to penetrate difficult soil, hardpan, and rocky layers with weak spots. It can even punch through asphalt and concrete pavement.
• The average tensile(pulling) strength of Vetiver roots is 75mpa, equivalent to that of nylon.
• As a wetland plant, Vetiver withstands prolonged submergence. Chinese research shows that Vetiver can survive longer than two months under clear water.
• Vetiver maintains a high tolerance to herbicides and pesticides, heavy metals, and soil conditions such as medium-high levels of acidity, alkalinity, salinity, sodicity, and magnesium content.

Australia - This farm reservoir was very badly constructed. A narrow line of vetiver was planted along the top of the wall, at the time of breaching the earth wall below the vetiver was not washed out. The breach occured where the vetiver had not been planted. Note the thick and massive vetiver root system that has prevented wash out. The roots reach right down to the bottom of the photo.

Photo 1 - Here the vetiver, planted in close rows across the spillway reduces the velocity and power of water passing down this spillway

Photo 2 - Australia - Just after the fire. Note the immediate regrowth.

Photo 3 - Australia - 2 months after the fire. The Vetiver will soon be back to its full strength and size.
