Rue has been grown in gardens since ancient times. This slightly toxic herb was once used as an insect repellant. The lacy, blue-green foliage and greenish-yellow flowers make it a terrific companion plant for almost anything. It can even be pruned for a formal look.
Ruta graveolens is a food source for black swallowtail butterfly larvae. Wear gloves when handling rue since it can cause rashes. Hardy in zones 5-10.
