Plant Profile: Ruta graveolens

Rue is a perennial herb that typically reaches heights and widths of 2 to 3 feet, characterized by its aromatic, evergreen, fern-like leaves. This resilient plant thrives in full sunlight and prefers moderately fertile, moist, and well-drained soil. It is known for its hardiness, being resistant to deer and capable of withstanding drought as well as dry, rocky conditions. However, it is important to avoid overly wet soils and to apply mulch during the winter months in northern climates. In early spring, it is advisable to prune the plants back to old wood. Often cultivated for its striking blue-green foliage, rue also serves as a host plant for various swallowtail butterflies. While its lifespan is relatively short, averaging around five years, it compensates by self-seeding to ensure its continuation. In spring, it produces clusters of yellow flowers that rise above the leaves.

**Diseases, Insects, and Other Plant Issues:**
Rue does not typically face significant insect or disease challenges. However, root rot can develop, especially in soils that do not drain well. When pruning or handling the plant, it is recommended to wear long sleeves and gloves for protection.
