Rue Jackman’s Blue herb is a small tough perennial shrub that has blue green soft foliage with yellow flowers during summer and a strong aromatic fragrance. The scent of Rue leaves repels ants, beetles, flies and is reported to ward off fleas. Rue plants can even be planted to keep cats and dogs away from your flower and vegetable garden due to their dislike of the smell.
When the plant blooms, it produces hundreds of black seeds that are easily collected to spread around your yard. The tough perennial shrub can be trimmed into a low hedge.
This herb always looks good even in full sun where I grow it. It is definitely a plant for a lazy gardener. This colourful plant is not suitable to grow in tropical climates.
