Frequently Asked Questions
Q1 What's the difference between Greek and Italian oregano?
Greek oregano (Origanum vulgare hirtum) is the pungent, flavorful culinary variety — sharp, spicy, peppery. Italian oregano is a milder hybrid. Common oregano (plain O. vulgare) is often flavorless. Buy labeled "Greek" or "hirtum" for cooking; anything else may be bland.
Q2 Does oregano come back every year?
Yes — reliable perennial in zones 4–10. Dies back to the ground in cold winters but returns vigorously in spring. Replace every 4–5 years as plants get woody. Propagates easily from cuttings or division.
Q3 When is the best time to harvest oregano for drying?
Just before flower buds open — essential oils peak in intensity. Cut stems in the morning after dew dries. Hang upside-down in a dark, airy spot for 1–2 weeks until crumbly. Dried oregano is often more flavorful than fresh.
