Caper bushes require full sunlight and soil with good drainage. The perennial plants can be grown from seeds cultivated in a pot with bricks or rocks placed in the bottom or from cuttings. Caper bushes require watering until the deep root system is established. Subsequently, they thrive in dry conditions.
Caper bushes are grown in the wild in arid climates found in the Mediterranean, East Africa, the Pacific Islands and Australia. The plants often grow on bare rocks or in sandy terrains. The plant produces edible flower buds and caper berries. The pickled buds have a salty taste and are often used in Mediterranean cuisines.
