Capparis spinosa is an evergreen perennial shrub known from ancient times. During the last years it has been intensively studied because of its multiple uses. The phenological growth stages of caper plant were described using the BBCH scale (Biologische Bundesanstalt, Bundessortenamt and CHemical industry). The decimal code established nine principal growth stages using a two-digit numerical system, and every major stage was in turn subdivided into secondary growth stages.
