Rosmarinus officinalis - rosemary

Rosmarinus officinalis


The latin name Rosmarinus is a compound word: “Ros” means “Dew” and “Marinus” means “of the sea”. So Rosmarinus stands for “Dew of the Sea” as the plant grows well near the sea-coast and sea-foam sprays upon it.
Officinalis (meaning ‘of the workshop’) is a common species name and it denotes medicinal plants.
