An intensely bitter herb, rue has faded from the culinary scene except in Ethiopia. Once widely used in the Mediterranean region and an important herb during the Roman Empire, it is still occasionally called for in traditional recipes and also appears as a flavoring in some distilled beverages. It should always be used fresh, so you will need it in your garden if you wish to use it. A common decorative, it can be found in the herb section of most well stocked nurseries and is easy to grow in temperate climates. The blue-green leaves are very small, about 3/8 inch long.
Rue has a place in herbal medicine as a digestive remedy and can also be
used as a cat repellant - most cats don't like the smell.
