Marjoram and oregano are mostly native to the Mediterranean region, but have been naturalised in many parts of the world. The two names are interchangeable – what we know as wild marjoram (Origanum vulgare) in Ireland is known as oregano in Europe, and both names are still used to describe the bought herb and cultivars of the wild plant.Origanum has strongly scented leaves and bears small white, pink or purple flowers. The leaves are commonly used in Greek and Italian dishes. Plants are easy to grow provided they are given plenty of sunshine and a well-drained soil. The flowers are well-loved by bees.Origanum vulgare ‘Aureum’ is known as golden marjoram. It bears golden, scented leaves and clusters of pink flowers in summer.
