The pomegranate (Punica granatum) is a fruit-bearing deciduous shrub in the family Lythraceae that grows between 5 and 10 metres (16 and 33 feet) tall. The pomegranate fruit husk is red-purple in color, with an outer, hard pericarp, and an inner, spongy mesocarp (white "albedo"), which comprises the fruit inner wall where seeds attach. Pomegranate seeds are characterized by having sarcotesta, thick fleshy seed coats derived from the integuments or outer layers of the ovule's epidermal cells. The number of seeds in a fruit can vary from 200 to about 1,400. Rich in symbolic and mythological associations in many cultures, the pomegranate is thought to have originated from Afghanistan and Iran before being introduced and exported to other parts of Asia, Africa, and Europe. This photograph, which was focus-stacked from 10 separate images, shows a whole pomegranate fruit (right), and a fruit split open to reveal the arils, each of which surrounds a seed (left).
