Common Rue is a striking ornamental herb prized for its attractive blue-green foliage, drought tolerance, and unique fragrance. Native to the Balkan Peninsula and long cultivated throughout the Mediterranean, rue makes an excellent addition to herb gardens, pollinator gardens, and dry landscapes. Its evergreen foliage provides season-long interest and thrives in hot, sunny locations where many other plants struggle.
Rue has a long history of medicinal use, but all parts of the plant may be toxic if ingested and may cause skin irritation or photosensitivity in some individuals. Wear gloves when handling plants.
