Capparis spinosa, the caper bush, also called Flinders rose, is a perennial winter-deciduous plant that bears rounded, fleshy leaves and large white to pinkish-white flowers. The plant is best known for the edible flower buds (capers), often used as a seasoning, and the fruit (caper berry), both of which are usually consumed pickled. Other species of Capparis are also picked along with C. spinosa for their buds or fruits. Other parts of Capparis plants are used in the manufacture of medicines and cosmetics. Capparis spinosa is present in almost all the circum-Mediterranean countries, and is included in the floristic composition of most of them, but whether it is indigenous to this region is uncertain. Although the flora of the Mediterranean region has considerable endemism, the caper bush could have originated in the tropics, and later been naturalized to the Mediterranean basin.
