Growing oregano

Oregano is an easy perennial for sun and well-drained soil. Greek oregano has the strongest flavor. Grow it from young plants or divisions, and trim it to keep it bushy.

Questions about oregano

Does oregano spread?

It grows into a wide clump and can seed itself. Trim it after flowering and divide large clumps every few years.

Is oregano the same as marjoram?

They are close relatives. Marjoram is milder and sweeter, and less hardy in cold winters.
