About Oregano
Oregano and marjoram are closely related and frequently confused, both in gardens and in shops. What is sold as oregano is usually Origanum vulgare, and its flavour varies enormously depending on where the plant grew: Greek and Italian forms raised in hot, dry, poor conditions develop far more of the aromatic oils than the same species grown in rich, damp soil, which can be almost bland. The name comes from Greek roots often glossed as "joy of the mountain". It is a spreading perennial that can colonise ground by runners, and it flowers freely, drawing bees.
Growing notes
- Greek oregano (subsp. hirtum) has the best culinary flavour — many seedling-grown plants are bland
- Drought tolerant once established
- Always consult a qualified medical or herbal practitioner before medicinal use.
