Ruta graveolens

Rue (Ruta graveolens) is a perennial herb native to the Balkan Peninsula. It is a small plant, growing to a height of about 30-60 cm (12-24 inches), with blue-green leaves and small, yellow flowers. The leaves have a strong, pungent aroma, and the plant is often used as a natural insect repellent.

In terms of growing conditions, Rue prefers well-drained soil and full sun. It is drought-resistant and can be grown in a variety of climates, though it may not do well in extremely hot or humid conditions. To cultivate Rue successfully, a grower should plant it in a location that receives plenty of sunlight, and ensure that the soil is well-drained.

Rue is not generally considered to be edible, and can cause skin irritation and other negative effects if ingested. However, it has been used medicinally in the past, and is sometimes used as a natural insect repellent or as a source of blue dye. It is also sometimes used in traditional witchcraft.

In terms of its value to wildlife, Rue is a good source of nectar for bees and other pollinators, and its strong aroma may help to repel pests from nearby plants. It is not known to have any significant value as a food source for animals.
