Understanding Rosemary and Its Companion Plants
Rosemary (Salvia rosmarinus) is a fragrant, evergreen herb native to the Mediterranean region. Known for its culinary uses and aromatic properties, rosemary is not only a valuable addition to gardens but also plays a crucial role in companion planting. Companion planting involves growing different plants in proximity for mutual benefits, such as pest control, pollination, and improved growth.
