Pomegranates (Punica granatum) are steeped in history and have been grown for thousands of years through the Mediterranean regions of Asia, Africa and Europe. Native from Iran to the northern Himalayas, the fruit eventually traveled to Egypt, China, Afghanistan, Pakistan, Bangladesh, Iran, Iraq, India, Burma and Saudi Arabia. It was introduced to the Americas in the 1500s by Spanish missionaries. A member of the Lythraceae family, pomegranate fruit has a smooth, leathery, red to pink skin surrounding the edible arils. These arils are the edible part of the fruit and are its seeds surrounded by sweet, juicy pulp. The seeds can also be used for planting. Pomegranate trees are grown not only for their juicy, tempting fruit, but also make attractive ornamental specimens with orange-red blossoms prior to fruiting, set off upon glossy, deciduous green leaves. Trees usually have thorns, and are grown as a bushy shrub. That being said, pomegranates can be trained as a small tree ideal when growing a pomegranate in a pot.
