Society garlic, scientifically known as Tulbaghia violacea, is a perennial plant native to the grasslands of Southern Africa. This plant forms attractive clumps of slender, grass-like foliage, from which delicate, star-shaped lilac-purple flowers emerge on tall stems. While its common name suggests a connection to traditional garlic, Tulbaghia violacea belongs to the Amaryllidaceae family, which also includes onions. The plant’s distinctive garlic-like scent is particularly noticeable when its leaves are bruised. Society garlic offers both ornamental beauty and practical uses.
Culinary Uses
Society garlic provides a flavorful alternative to traditional garlic. Both the leaves and flowers are edible, offering a milder, more subtle garlic taste without the intense aftertaste of common garlic. This makes it a versatile ingredient for those who prefer a gentler profile.
The grass-like leaves can be chopped like chives, adding a fresh, garlicky note to dishes. They are excellent in salads, stir-fries, soups, and egg dishes, or as a garnish. The vibrant, star-shaped flowers also contribute a peppery, onion-like sweetness and make an appealing garnish. Historically, the Zulu people in South Africa traditionally used the leaves and flowers to season meat and potato dishes; bulbs were also consumed.
Medicinal and Health Properties
Beyond its culinary appeal, society garlic has a history of use in traditional medicine for its health-supporting properties. Indigenous communities, including the Zulu, have long utilized the plant for various ailments. Extracts have traditionally addressed conditions such as colds, coughs, sinus headaches, fevers, and intestinal worms.
The plant contains sulfur compounds, flavonoids (quercetin, kaempferol), and saponins. These constituents contribute to its antimicrobial, anti-inflammatory, and antioxidant effects. Research suggests Tulbaghia violacea may support cardiovascular health, potentially lowering blood pressure. However, excessive consumption or high dosages have been associated with adverse effects.
Garden and Landscaping Advantages
Society garlic offers numerous benefits for gardeners as both an ornamental and practical landscape plant. Its strong, sulfurous scent acts as a natural deterrent against common garden pests, including:
Aphids
Slugs
Snails
Deer
Moles
Voles
Planting society garlic near susceptible plants can help protect them, making it an excellent companion plant. Some traditions use it to deter snakes.
Its aesthetic appeal is a significant advantage. Its tidy, clump-forming habit and narrow foliage provide attractive texture to garden beds. Delicate, star-shaped flowers in shades of lilac and purple emerge on tall stalks, blooming from early summer into autumn, adding continuous color. Society garlic is commonly used as:
A border plant
In rock gardens
For mass plantings
As ground cover
In containers
Gardeners appreciate society garlic for its low maintenance and adaptability. It is easy to care for, suitable for both experienced and novice gardeners. Once established, it demonstrates drought tolerance, requiring minimal watering.
While it prefers well-drained, sandy soil, it can adapt to various soil conditions. Society garlic performs best and flowers most profusely in full sun but can tolerate partial shade, though flowering may be reduced. It is winter hardy in USDA Zones 7-11.
