It is the most widespread of the 23 species and subspecies of Capparis, at least 19 of which are used for food and medicine. They range wide from the Eastern Mediterranean, eastward through much of southern Asia, Australia and Pacific Islands.The familiar caper is the immature flowerbud of the plant preserved in vinegar or salt brine.
