The pomegranate is a shrub or small tree growing between 1 to 10 m tall, with multiple spiny branches, and is extremely long-lived, with some specimens in France surviving for 200 years. The leaves are opposite or almost opposite, glossy, narrow oblong, entire, 3–7 cm long and 2 cm broad. The small flowers are bright red with three to seven petals. Some fruitless varieties are grown for the flowers alone. The edible fruit is a berry, intermediate in size between a lemon and a grapefruit, 5–12 cm in diameter with a rounded shape and thick, reddish skin. The number of seeds in a pomegranate can vary from 200 to about 1400. Each seed is surrounded by a water-laden edible pulp, ranging in color from white to deep red or purple. The seeds are embedded in a white, spongy, astringent membrane.
