Greek Oregano is a perennial to two feet high, which spreads to form a dense cluster. The leaves and calyces are usually covered with glandular dots, and the stems with rough, coarse, glandular hairs. The plant has a very pungent penetrating smell. (Wild Marjoram, which is often mistaken for Oregano, does not have glandular hairs and has a weak musty odour.) Great aromatic flavouring for cooked foods and salads. Good companion plant.
