Punica granatum has been widely planted as an ornamental in the western and southwestern United States and has naturalized around old homesites. It has been cultivated for centuries in warm regions of the world, probably having originated in the Middle East in the area of modern Iran, Afghanistan, and Iraq. The seeds are eaten in salads and other dishes, especially in Mediterranean cuisines. Juice expressed from the fruit rind and seeds is currently a popular beverage in North America, drunk for its antioxidant and anti-inflammatory properties. Dwarf (‘nana’) and double-flowered forms are also cultivated.
