The caper bush, scientifically known as Capparis spinosa, is a perennial plant native to the Mediterranean region. It typically grows in rocky, dry areas and can reach heights of about 1 meter. The bush produces large, white to pink flowers and green, round buds that are harvested for culinary use. The buds of the caper bush are pickled and used as a flavorful condiment in various dishes, adding a tangy taste. Additionally, the plant's leaves and fruits are also edible and can be used in salads or as a garnish. Caper bushes thrive in sunny environments and are drought-resistant.
