Licorice (Glycyrrhiza Glabra) - Licorice is a tall, shrub-like perennial that readily establishes from herb seeds. It is attractive growing in the herb garden with lavender-blue flowers in the summer and early fall. The Licorice herb plant is a legume and is native to Southern Europe and parts of Asia. It is the Licorice root that is harvested for both culinary and medicinal use. It is not related to anise, star anise, or fennel, which all have a similar taste. It is also commonly called Spanish Licorice.
Licorice, or sometimes spelled Liquorice, grows best in sub-tropical climates, in rich, well-drained soils, and in full sun. Once the plant is three years of age, the roots are harvested in the autumn. Commercially, Licorice root is used to make candy, liquor, as a sweetening in teas and to make extracts. The extracts are used to flavor soft drinks, tobacco, and pharmaceutical products.
The Licorice medicinal herb has been used for centuries. Teas made from the root are used to soothe sore throats and coughs. Licorice also has anti-inflammatory properties and is used for arthritis pain and inflammation. It is a mild laxative and seems to soothe gastrointestinal conditions.
How To Grow Licorice From Herb Seeds: Start the Licorice seeds in the early spring indoors. It is recommended to soak the seed in tepid water for 24 hours before sowing. Keep the herb seeds moist but not soggy until germination occurs. Transplant the Licorice herb plants outdoors after danger of frost has passed. Space the plants 24 - 36 inches apart in the herb garden.
