Vetivergrass (Zizanioides)

The Vetivergrass (Zizanioides) is generally described as a perennial graminoid. This is not native to the U.S. (United States) and has its most active growth period in the year round . The greatest bloom is usually observed in the late summer, with fruit and seed production starting in the fall and continuing until fall. Leaves are retained year to year. The Vetivergrass (Zizanioides) has a long life span relative to most other plant species and a rapid growth rate. At maturity, the typical Vetivergrass (Zizanioides) will reach up to 7 feet high, with a maximum height at 20 years of 0 inches.

The Vetivergrass (Zizanioides) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by bare root, container, seed, sprigs. It has a slow ability to spread through seed production and the seedlings have low vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 14°F. has high tolerance to drought and restricted water conditions.
