Mediterranean type oregano is a perennial herbaceous plant with small purplish flowers that grows to about 1 to 2 feet tall.  It is native to temperate western and southwestern Eurasia and the Mediterranean region. The plant can also be grown in colder climates but often does not survive the winter. Leaves are typically harvested right before the flowers bloom.  

Oregano is the name given to many species of perennial herb belonging to the genus Origanum, including the major species Origanum vulgare which is grown for its leaves which are commonly used as a herb in cooking. Oregano plants can be woody or herbaceous and possess multiple branching stems. The leaves are oval or round and are arranged alternately on the stems. The plants produce small pink, purple or white flowers and small oval, brown fruits and can reach up to 1 m (3.3 ft) in height. Oregano is perennial and can be grown for 3–4 years but is commonly grown as an annual in northern climates. Oregano may also be referred to as European oregano or wild marjoram and originated from the Mediterranean.
