Origanum /əˈɹɪɡənəm/

Common name: Oregano · Wild marjoram

Origanum A genus of about 40 herbaceous perennials in the mint family, native to the Mediterranean, Middle East, and central Asia. Oregano and marjoram are the familiar members, valued for their strongly aromatic leaves and pink-purple flower clusters beloved by bees. These are sun-loving plants that prefer lean, sharply drained soil and suffer in wet, rich ground.

Fun facts

  • Oregano's flavor intensifies when the leaves are dried.
  • Oregano oil contains carvacrol, a compound with strong antimicrobial activity.
  • Oregano became widely popular in the United States after World War II, when returning soldiers craved Italian pizza.
