A caper is a perennial spiny bush that bears rounded, fleshy leaves and big white to pinkish-white flowers. A caper is also the pickled bud of this plant. The bush is native to the Mediterranean region, growing wild on walls or in rocky coastal areas throughout. The plant is best known for the edible bud and fruit which are usually consumed pickled. Other species of Capparis are also picked along with C. spinosa for their buds or fruits.
