Rue (Ruta graveolens)
Rue, also known as Herb of Grace, is a small shrubby perennial that grows 2 to 3 feet high with delicate blue-green foliage and small, bright yellow flowers. It is in the citrus family (Rutaceae) and is native to the Balkans and southeastern Europe where it is used as a bitter flavoring in traditional cuisines of the eastern Mediterranean.
Rue’s shrubby nature and charming foliage and flowers make it an excellent low-growing hedge, border, or container plant. The yellow flowers that bloom in June and July attract butterflies, but the highly fragrant leaves give off a strong aroma when crushed and can also repel insects. Planted in the garden, Rue is an effective insect-repelling companion. It is the national herb of Lithuania, and in southeastern Europe, it developed a reputation as a magical protective herb and was often planted in doorways to ward off evil spirits.
Rue is a fast-growing, low-maintenance plant. It is deer-resistant and drought-tolerant after it is established and will grow in a variety of soils as long as they are well-draining. It does best in full sun but will tolerate light shade and is hardy in USDA zones 4 to 10.
