Rue (Ruta graveolens) is a perennial herb with a strong odor, small greenish-yellow flowers and blue-green leaves. It is native to Southern Europe. It is also known as common rue or herb-of-grace. Rue is both a culinary herb and a medicinal herb.

- The juice of the rue plant has also been used to treat earaches.
Caution: In large doses, however, it can be toxic, and it should never be used by women who are pregnant or nursing.
Other Uses:

- The dried leaves are also an effective moth repellent.
- When mixed as a decoction, it can be used topically to kill lice and fly larvae.

Growing Rue
Indoor Sowing: Early Spring.
Direct Sowing: Spring and Autumn.
- It is easy to start from seeds in the garden or in trays. Use a seed-starting mix that holds moisture but also drains well.
- Rue seeds need light to germinate, so scatter rue seeds across the surface of the soil and then gently press the seeds into the soil with your hands.
- When the seedlings develop at least two sets of true leaves, they can be transplanted into the garden or into larger pots.
- Requires full sun or at least 6 hours of full sun.
- It grows best in well-drained soil and will even grow in rocky, dry soil where other plants struggle to survive.
- Rue needs regular but not excessive watering, depending on how much rain your area gets. In dry regions, water it once a week, making sure the soil dries out between waterings. In South Africa, studies show that rue does best with about 1.5 cm of water per week.
