Ruta graveolens - Rue

Traditional, aromatic, and wonderfully distinctive, Ruta graveolens is an old-fashioned herbaceous perennial with finely divided blue-green foliage and a bold garden presence. Commonly known as rue, this easy-care perennial has been grown for centuries in herb gardens, cottage gardens, Mediterranean-style plantings, and drought-tolerant landscapes. Its soft, ferny leaves bring cool color and texture to sunny beds, while small yellow flowers add a cheerful seasonal note and attract beneficial insects.

Growing approximately 2 to 3 feet tall and wide, Ruta graveolens forms a rounded, shrubby mound that works beautifully as a textural accent, informal edging plant, or companion in sunny mixed borders. Its blue-green foliage pairs wonderfully with lavender, salvias, santolina, yarrow, rosemary, thyme, ornamental grasses, and other drought-tolerant perennials that create a layered, water-wise garden scene. It is especially useful where gardeners want structure, fragrance, and foliage contrast rather than relying on flowers alone.

Plant Ruta graveolens in full sun in well-drained soil, with low to moderate watering once established. Tough, deer-resistant, and well-suited to dry garden conditions, rue is a resilient choice for gardeners who appreciate useful, historic, and beautifully textured plants. Handle with care, as the foliage may irritate sensitive skin. Explore more long-lasting favorites in our Perennials & Biennials collection.
