Tulbaghia violacea (society garlic, pink agapanthus) is a species of flowering plant in the onion family Alliaceae, indigenous to southern Africa (Natal and Cape Province), and reportedly naturalized in Tanzania and Mexico.
Growing to 60 cm (24 in) tall by 25 cm (10 in) wide, it is a clump-forming perennial with narrow leaves and large clusters of fragrant, violet flowers from midsummer to autumn (fall).
When grown as an ornamental, this plant requires some protection from winter frosts. It has gained the Royal Horticultural Society's Award of Garden Merit.
T. violacea is used locally as a herbal remedy/medicine to treat several ailments. Recently it was demonstrated to have androgenic and anti-cancer properties in vitro.
T. violacea exhibited antithrombotic activities which were higher than those found in garlic.
