- 🌱 The plant is native to the arid regions of Mexico and the southwestern United States, where it thrives in harsh conditions with minimal water—perfect for xeriscaping and low-water gardens.
- 🌱 Mexican oregano contains higher thymol and carvacrol concentrations than some Mediterranean oreganos, giving it a more robust antimicrobial profile and distinctive warm, peppery flavor.
