Black Pepper is the dried mature berry of Piper nigrum, a climbing, perennial shrub mostly found in hot, moist region of Southern India. Under cultivation pepper vines are trailed over support as columns, 5-6 mtr tall, 1-2 meter diameter. The climbing woody stems have swollen nods with clinging roots at each node, which helps in anchoring the vine to the support trees (standards). It has straight upward growing main stem and have lateral shoots from the axils of the leaves having shorter inter nodes without adventitious roots. In such branches, the terminal buds get modified into an inflorescence (spike) and the auxiliary buds continue further growth.
