Growing directions
Oregano is a hardy Mediterranean perennial with bold, aromatic leaves that are a cornerstone of Italian and Greek cooking. Surface sow the fine seed indoors and leave it uncovered under light, keeping it barely moist until sprouts appear. Transplant into lean, well-drained soil in full sun, where the plant develops its strongest flavor. Harvest sprigs regularly and shear plants back after flowering to keep them compact and productive for years.
