Most people think of licorice as a flavor. If asked to come up with licorice in its most basic form, you might very well pick those long, ropy black candies. But where does licorice come from? Believe it or not, licorice is a plant, known for its strong and sweet flavor. Keep reading to learn more about growing licorice and licorice plant care.

Licorice Plant Information

What is a licorice plant? Related to peas and beans, licorice (Glycyrrhiza glabra) is a flowering perennial that grows to about 5 feet tall. Its scientific name, Glycyrrhiza, comes from the Ancient Greek words glykys, meaning “sweet,” and rhiza, meaning “root.” Just like the name suggests, the part of the plant that contains that distinctive flavor is its extensive root system.

Native to Eurasia, it has a long history of use from China to Ancient Egypt to Central Europe both as a sweetener (it is 50 times sweeter than sugar) and as a medicine (even today it is widely used in throat lozenges). To harvest the plants, the roots are dug up and squeezed of their juice, which is boiled down to an extract.

Licorice Plant Care

Can you grow licorice plants? Absolutely! Licorice is very common in the wild in Eurasia and parts of North America, but it can also be cultivated. You can either plant seeds in a greenhouse in the fall, transplanting them outdoors in spring, or (and this is much easier) divide the rhizome of an older plant in the spring. Just make sure that each section of rhizome has a bud attached to it.

Licorice plant care is not difficult. The plants like alkaline, sandy, moist soil. Cold hardiness varies greatly from species to species (American licorice is the toughest, hardy down to zone 3). Licorice plants are slow to get established, but once they get going, they can become aggressive. Keep your plant in check by harvesting its rhizomes regularly.
