Rosemary Oil is steam distilled from the flowers, leaves and twigs of wild growing Salvia rosmarinus (was Rosmarinus officinalis), which is found in numerous forms and sub-varieties. The shrub is evergreen with leaves similar to hemlock needles. It is native to the Mediterranean and Asia, but is reasonably hardy in cool climates. It can withstand droughts, surviving a severe lack of water for lengthy period.
