The word “rue” means “to regret,” and the herb of the same name is associated with regret, sadness and bitterness in biblical writings and literature. Rue (Ruta graveolens) is a bitter herb native to the Mediterranean and Southern Europe. It has evergreen bluish-green leaves that grow in groups of six or seven off the semi-woody branches. The mature plant reaches about 2 1/2 feet tall. The leaves smell bitter and medicinal when cut or crushed. Rue produces many small four-petalled flowers in mid- to late-summer. The foliage has an almost lacy look to it, although the leaf sections are not thin and pointy but rounded.

Rue is easy to grow. The tiny seeds, if strewn onto a garden plot or a container of potting soil and covered with a light sprinkling of soil and moistened, will sprout in a week or so. Tiny light green seedlings look delicate, but are sturdy and will grow quickly into a foot-tall plant. Pinching the tops will make them grow bushier. Rue will grow well outdoors in poor or rich soil, with little attention. Inside as a houseplant, rue needs regular watering and bright light to grow well. During mid-summer, it will produce tiny yellow flowers at the tops of the plants, which turn into hard green seed-heads that dry into brown husks and open to reveal and drop many tiny black seeds.

Snip off dried seed-heads into a plastic bag to collect seeds for planting next season or for giving away. Crushed rue seed can be added to soups, salads and sauces for seasoning and flavoring.
