Rue is an aromatic and medicinal perennial plant with finely cut blue-green foliage, highly valued for its graphic appearance and powerful scent. Its compact, bushy habit adds beautiful texture to herb gardens, sunny borders, rock gardens, and Mediterranean-style landscapes. Its light and bright yellow blooms add a natural touch to the garden while attracting certain pollinators.

Easy to cultivate, rue prefers a full sun location in light, poor to moderately fertile, and very well-drained soil. It tolerates heat and drier conditions well once established, making it a good plant for low-water gardens. Light pruning after flowering helps maintain a denser, more compact, and well-structured plant. As its foliage can be irritating to the skin for some people, it is recommended to handle it with gloves.

Traditionally recognized as a medicinal and aromatic plant, rue is primarily cultivated today for its ornamental interest, fragrant foliage, and high resistance. It pairs well with lavenders, thymes, sages, santolinas, rosemarys, and other sun-loving plants. It is a unique perennial for gardeners looking for a robust, decorative, and characterful plant in an aromatic or naturalized garden.
