Fun Facts
- 🌱 Rosemary's name comes from Latin 'ros marinus' meaning 'dew of the sea,' as it naturally grows along Mediterranean coastlines. It has been used for thousands of years in cooking and traditional medicine.
- 🌱 Lavender is one of the most versatile herbs with over 450 species and cultivars; the fragrance comes from volatile oils that increase in potency after the plant is dried.
- 🌱 Both herbs are naturally allelopathic, meaning they release compounds that can inhibit the growth of some competing plants nearby—this is why they pair well with certain garden companions but not others.
