Licorice flowers, often an overlooked aspect of the familiar licorice plant (Glycyrrhiza glabra), contribute to the plant’s overall lifecycle and aesthetic. While the plant’s roots are widely celebrated for their distinct sweetness, the flowers themselves possess their own set of characteristics. These blossoms provide a natural beauty that complements the plant’s more utilitarian underground parts.
Description of Licorice Flowers
The licorice plant, Glycyrrhiza glabra, is a herbaceous perennial reaching about 1 to 1.5 meters (3.3 to 5 feet) tall. It features compound leaves, usually 7–15 cm (3–6 inches) long, with 9–17 leaflets. The flowers are relatively small, measuring approximately 8–12 mm (5/16–1/2 inch) in length.
These delicate, pea-like flowers emerge in loose, erect clusters or spikes, often 10 to 15 cm (4 to 6 inches) long. They display hues including pale blue, purple, blue-violet, or sometimes white-pink. Flowering occurs during the summer months, from June to July. The flowers do not possess the strong, distinct licorice aroma commonly associated with the plant’s roots.
Edibility and Safety
The flowers of the Glycyrrhiza glabra plant are not commonly consumed. While the licorice plant is broadly categorized as “edible,” this primarily refers to extracts and oils derived from its root. The root contains glycyrrhizin, the compound responsible for its intense sweetness, which is approximately 50 to 170 times sweeter than sugar.
The entire licorice plant, including its aerial parts, possesses a moderate level of toxicity due to glycyrrhizin. Consuming large amounts or using it for prolonged periods can lead to adverse effects such as high blood pressure, low blood potassium levels, fluid retention, and muscle weakness. It is advised to avoid consuming licorice during pregnancy. Caution is prudent regarding their consumption.
Traditional and Modern Applications
While the licorice plant is primarily cultivated for its roots, which are extensively used in food, beverages, and traditional medicine, its flowers also contribute to its appeal. The flowers add an ornamental dimension to the plant, with their attractive blue, purple, or white hues, enhancing visual interest in a garden.
Beyond their aesthetic value, these flowers serve as a source of nectar for pollinators, contributing to local ecosystems. In traditional contexts, the licorice plant’s roots have a long history of use in various herbal practices, including Chinese and Ayurvedic medicine, for a range of ailments from respiratory issues to digestive discomfort. However, the flowers themselves do not hold significant traditional medicinal or culinary applications separate from the root. While some perfumery notes are labeled “licorice flower,” this typically refers to an anise-like aroma recreated from compounds found in the root or other plants, rather than a direct extraction from Glycyrrhiza glabra flowers. The primary applications of the licorice plant continue to center on its root for flavoring and medicinal extracts.
