When you want to get blue, get rue.
Rue is an interesting and lovely herbaceous shrub that will add a unique blue-green foliage accent to your garden. A small evergreen semiwoody perennial that matures to about two feet tall and wide, rue has been used as a medicinal and "antimagic" herb for centuries, and was even considered a reliable defense against witches.
Quite drought-tolerant once established, rue thrives in poor sandy soils and hot, dry sites that receive full sun. Good drainage is a must.
Rue was formerly used to treat many common human ailments, but modern herbalists now question its effectiveness as well as its safety. In fact, some people are allergic to rue and get a skin rash from handling the plant, especially on hot days. Consuming large amounts of rue can cause violent stomach pain, vomiting, and convulsions. Pregnant women should never ingest it.
Rue is a symbol of regret, sorrow and repentance, and Catholics used sprigs of it to sprinkle holy water on worshippers. On the light side, the rue leaf was the model for the suit of clubs in playing cards.
'Jackman's Blue,' a popular cultivar in Europe, has beautiful bluish green foliage and stays in a tight, rounded form. 'Blue Beauty' is smaller, with powdery blue foliage. 'Variegata' has white splashes on the leaves and is often used in floral arrangements.
Rue foliage has a strong, somewhat unpleasant scent when torn; for this reason, it is often used as a natural dog, cat and/or insect repellant. And it is supposedly really good at keeping witches away...a good thing to know as Halloween approaches.
