This Vetiver, from the southern India cultivars, produces few flowers and the seed from those flowers will not germinate in natural conditions. This is one of the most valuable characteristics of Vetiver when used in bioengineering applications – it is the assurance that the plant will not spread and become invasive in areas where it is introduced. Propagation is only done by means of root division, a process that you can see in our page Vetiver Production in this store. As a certified grower by The Vetiver Network International, we only propagate and sell plants known to be non-fertile. More information on this subject can be found on our blog post: Weed Potential of Vetiver.
Under favorable conditions, bare-root slips could be an option. An effective slip must have at least three growing tillers or shoots and have a well-developed root bundle. Under favorable soil and humidity conditions, most slips will develop into good plants. Replanting dead slips over the first 90 days can be laborious and expensive. You must ensure that no breaches remain in the hedges that may become an "Achilles tendon" to your hedgerow. Survival of bare-root plugs is seldom better than 80%.
Our plants have been hardened for a long time under nursery conditions and have a much greater root development. In difficult soils or conditions, our plants will perform better and will become a firm hedgerow in less time than slips. Bare-root slips will require more diligent watering and fertilization, but are a cost-effective alternative only for experienced users.
If you require a large number of bare-root slips, please contact us to discuss your requirements.
Yes, Chrysopogon zizanioides is the source of the Oil of Vetiver. The oil is produced commercially from its roots by means of a steam distillation process. For us not having that fancy equipment, the roots can be harvested from plants around a year old, washed well, and used in sachets or bundles to perfume lingerie drawers. The aroma is woody and subdued and will last several months. After harvesting the roots, the plant can be divided and replanted for the next year. More information on this subject can be found on our blog post: Vetiver Oil – The Oil of Tranquility.
Vetiver is a tropical plant, and will do well in tropical, subtropical and Mediterranean climates. The USDA considers it adapted to Zones 9 to 11. In the USA, the plant has been known to survive soil temperatures of 14 deg. F. but this is not a recommended environment. In borderline locations, cutting the plant down very close to the ground and mulching heavily has been effective for winter survival. In summary, if the soil is permanently frozen in winter, the plant will be killed - but it will survive a sporadic snowfall. More information on this subject can be found on our blog post: Cold Weather Tolerance of Vetiver. See our store page USDA Vetiver Grass Planting Zone Map for more information.
Once the plant is well established, it is not likely to die very easily unless affected by frost, herbicides, or physical damage. If a plant dies for any reason, its root system will decompose over time like any other vegetative matter. If you can’t wait, dig in six to eight inches into the soil with a pickaxe, and replace the plant filling in with fresh soil.
The Vetiver System (VS) recommends a distance of 4 to 6 inches between plants in order to ensure a strong hedgerow in the shortest possible time. Our plants have a well developed root system upon delivery and, in most cases, can be safely planted at the maximum 6-inch separation. Bare-root tillers should be planted at a 3 to 4-inch separation because the undeveloped root system will take much longer to become established and may also have a high mortality rate.
In most cases, you will not need a phytosanitary certificate. Our Vetiver plants are shipped in a potting mix composed of peat moss, perlite and vermiculite. No natural soil or sand is in the mix. Our plants will pass a USDA phytosanitary inspection if one were to happen for your order. It is your responsibility to check with your local regulatory agencies and determine if a certificate is required. We are not responsible for delays or confiscation due to the lack of proper documentation. Obtaining a certificate is an elaborate process and is not cost-efective for small orders. Contact us for cost and requirements should one be necessary.
Only if you are very patient. Even with the proper permits, Hawaii has a two-year quarantine on any and all grasses entering the state. The Vetiver Network International maintains a list of reliable suppliers and consultants around the world that you can find here: International vetiver grass suppliers. Several good sources in Hawaii are included.
If you are not on USA territory, we can not ship to you. The Vetiver Network International maintains a list of reliable suppliers and consultants around the world that you can find here: International vetiver grass suppliers.
Hopefully some day. For now, few stores will stock these plants and you may not be able to verify their provenance. Get your plants from reputable growers that are members of The Vetiver Network International.
