Mint Family (Lamiaceae / Labiaceae)
Greek oregano is one of many perennial herb species in the genus Oreganum native to the Mediterranean region. It tends to get woody over time.
This mid-summer blooming plant loves full sun, hot temperatures, and well drained dry soil. It grows up to about 24 inches tall and 18″ wide and will survive to USDA planting zone 5.
Good Greek oregano should have a very spicy intense flavor. Taste the leaves before you buy this plant.
Be careful not to confuse ornamental oregano (Oreganum laevigatum) with Greek oregano for culinary use. The ornamental type has little flavor.
