Description
Rue is a small-growing, shrub-like perennial herb with a brief life span. It has blue-green, fragrant leaves that resemble ferns. Additionally, it features clusters of tiny yellow blooms in the summer that draw parasitic wasps, butterflies, and other pollinators to the garden. Planting the ornamental herb in the spring, after the risk of frost has gone, is advised due to its moderate growth rate.
Habitat
It is indigenous to the Balkan Peninsula. Grown in gardens all around the world, it’s valued for its bluish foliage and occasionally for its ability to withstand hot, dry soil.
Uses
To treat headaches and ear pain, crushed rue leaves are inserted into the ear canal. Rue is used externally as a skin antibacterial, insect repellent, and poultice for rheumatic discomfort.
Varieties
There are various types of rue, such as:
‘Blue Beauty’: The leaves of this plant are a particularly vibrant blue-green.
“Jackman’s Blue“: This cultivar has a powerful scent and a deep blue color.
“Variegata“: This variety’s leaves contain a hint of white.
Plant Care
- Light
Full daylight, or at least six hours of direct sunshine most days, is ideal for rude growth. However, some shadows are OK as well. But in the shadow, plants will yield fewer flowers.
- Soil
Good drainage is essential for the health of rue plants. To aid with drainage, add sand, perlite, or vermiculite to the soil. You can also utilize raised beds with prepared soil in gardens that are mostly made of hard clay. Although it can handle poor soils, rue prefers a somewhat rich soil. It also grows in soil with a pH range of slightly acidic to slightly alkaline.
- Water
Once established, common rue is an excellent choice for a rock garden or xeriscape because of its extreme drought tolerance. Except during extended dry spells, you won’t need to water. Refrain from overwatering as this can lead to root rot.
- Temperature and Humidity
Rue plants are native to Greece, Turkey, and Italy, where they grow best in hot climates with minimal humidity. As long as the plants have adequate air circulation and soil drainage, they can tolerate some dampness.
- Fertilizer
Rue plants should not be fertilized. The plants will grow more foliage at the expense of the blooms if there are too many nutrients available.
