Black Pepper is known chiefly as a food plant; its berries are the most widely consumed of all seasonings (black and white pepper). It is also a rewarding and, above all, undemanding ornamental climbing plant. It is native to tropical Asia where it reaches a height of 10 m (33 ft). Theare alternate, heart-shaped and dark green. The green are extremely small and arranged in drooping clusters. They do not have a perianth; the two stamens have short filaments and the lobed stigma is pressed close to the globose ovary. Pepper plants with coloured are also grown; for example P. orna-tum with young leaves coloured carmine-red that later fade to greyish-pink, P. porphyrophyllum and P. sylvaticum.
P. nigrum may be placed in a light, but it tolerates shade very well. The winter temperature should be about 15°C (59° F). The growing medium is usually a loam and peat . Water regularly to keep the permanently moist. The plant also benefits from misting. Feed weekly from spring to autumn. Propagate by and tip which require a temperature of about 25° C (77° F) for rooting. Always put several in one pot and cover them with a plastic bag, otherwise the plants will shed their leaves. All variegated species are more tender; in winter the temperature should not fall below 18°C (64° F).
