What Is Rosemary? A Complete Guide to This Aromatic Plant

Rosemary is an evergreen aromatic shrub in the mint family, Lamiaceae, native to the Mediterranean coast of Europe and now cultivated all over the world. The whole plant carries a rich fragrance, and its slender, needle-like leaves make it one of the most familiar culinary herbs.

In appearance, rosemary has noticeably woody stems and linear leaves that are dark green on the upper surface and slightly silvery-gray beneath, with a leathery feel to the touch. When well cared for, it produces small pale blue-purple or white flowers scattered among the branches and leaves, giving it considerable ornamental value as well.

Rosemary has a remarkably wide range of uses. In Western cuisine, its sprigs are often used to add flavor to dishes such as roast meat and roast potatoes; once dried, the leaves can also be brewed into herbal tea. In addition, its aromatic compounds are often extracted to make essential oils and fragrances, and it is equally suitable for growing as a potted plant or a garden plant for ornament. In the language of flowers, rosemary is often associated with remembrance and commemoration, so many folk names for it have been passed down as well.

Growing rosemary is not particularly difficult. It prefers a sunny, warm, dry environment, and a loose, airy, well-draining soil is best. In day-to-day care, the most important thing is to avoid overwatering, which causes waterlogging and root rot; during the growing season, light pruning also encourages branching and makes the plant fuller and more compact.
