Caper, may be a pickled flower bud used as a seasoning in salads and in sauces, as well as tartar sauce. The buds return from an occasional, trailing shrub known as the caper bush that grows primarily within the Mediterranean countries. The caper bush blooms early in summer and has pinkish-white flowers with four petals. The unopened buds are pickled in salt and vinegar to create the seasoning.

Scientific classification: The caper bush belongs to the caper family, Capparidaceae. Its scientific name is Capparis spinosa.
