Pepper or black gold has earned Kerala
transnational fame. The Malayalam name for pepper is kurumulaku. Pepper is the
berry of Piper nigrum, a climbing perennial shrub. It is usually grown in the
moist regions of south India. The creeper has swollen nods with clinging roots
on its either sides. It is grown on support trees and the roots help the
creeper to anchor on the trees. The single-seeded fruits grow spirally on
fleshy pedantries. The fruit is spherical in shape and green in colour, which
turns red on ripening.
The sun dried fruit is black pepper which is in high demand in the spice market. Besides the green pepper, white pepper is also sold in the market, which is the kernel after removing the skin. The skin is the most pungent part of the seed and hence white pepper is for those who want the less fiery variety. White pepper is used in products such as mayonnaise when the black specks of black pepper are not desired.
The other Indian states that grow pepper are Karnataka and Tamil Nadu.
Pepper is an inevitable ingredient for several culinary delights. Besides hot taste and aroma, it is added to dishes to correct the seasoning. Pepper is a good preservative which is used in baking, pickling, canning and for preserving meat.

Among plants, there are annuals and perennials. Annual plants complete their life cycle in one year. They grow from the seed, bloom, produce seeds and die in one growing season. Perennials live for more than two years and usually flower every year and set seeds.
Some perennials flower only once in their lifetime, set seeds and die. The next generation of the plants are established from these seeds and the cycle is repeated. Such plants are known as monocarpic, opposed to polycarpic plants that flower and set seeds many times during its lifetime. Monocarpic plants flower only after attaining maturity. The time taken by different species may differ in this respect.
Bamboos are monocarpic plants taking more than 40 years to mature and flower. Another characteristic shown by such plants is that these will flower gregariously in a single season. This happens in the case of bamboos and Kurinjis. The term 'plietesials' is used to refer to such plants. The time taken to mature varies in different species of Kurinjis. So different species of Kurinjis have different intervals of flowering. Neelakurinji matures in 12 years time and flowers gregariously every 12 years.
