Palmarosa
Extracted from the Wikipedia article Cymbopogon martinii.
Cultivation
Palmarosa grows in the wild in certain wetlands of India and Nepal. Palmarosa oil is extracted from the stem of the grass by distillation of dried leaves. Once the stems and leaves have been distilled for two to three hours, to separate the oil from the palmarosa plant matter, then the leftover grass residue is turned into manure or composted.
