An evergreen shrub with numerous branches, Rosemary's bark is ash-colored and scaly with leathery, thick leaves that are lustrous and dark green with white underneath. Its tiny pale blue blossoms abound from December through spring, and it can grow to heights of close to 2 meters in height. Its name means 'dew of the sea' because Rosemary naturally grows near the Mediterranean Sea. It has been used medicinally for several thousand years, and its leaves were traditionally burned to purify the air. Rosemary was used in Roman burial rites, and that practice continued well into the middle ages when it was customary to lay branches of rosemary on the coffin at funerals. Rosemary Essential Oil has a fresh strong, herbal woody scent.
