Plants > Ground Cover > Vetiver
Native to India. Vetiver can grow up to 1.5 metres high and form clumps as wide. The stems are tall and the leaves are long, thin, and rather rigid; the flowers are brownish-purple. Unlike most grasses, which form horizontally spreading, mat-like root systems, vetiver's roots grow downward, 2–4 m in depth. This plant can be extremely helpful for erosion control.
Benefits | Desirability
This is a great solution for soil erosion.
Vetiver is used as a flavoring agent but is mainly cultivated for the fragrant essential oil distilled from its roots.
Vetiver grass is used as roof thatch (it lasts longer than other materials), mud brick-making for housing construction (such bricks have lower thermal conductivity), strings and ropes andornamentals
