Rosemary is a fragrant herb that adds a wonderful aroma to any garden. Its needle-like leaves have a distinct pine-like scent that is both invigorating and calming. Rosemary is commonly used in cooking, particularly in Mediterranean cuisine, to add flavor to dishes like roasted meats and vegetables. It is also known for its medicinal properties, such as improving memory and concentration. Rosemary plants thrive in well-drained soil and full sun, making them an excellent choice for a courtyard herb garden.
