Coriander is a fast-growing annual herb grown for its fresh leaves and aromatic seeds used in cooking and spice production. In Kenya, the leaves are widely known as dhania and form an essential ingredient in many traditional dishes. The crop grows well in kitchen gardens and commercial herb farms across Kiambu, Nakuru, Nyandarua, Meru, Embu, and parts of Western Kenya. Coriander matures quickly and produces several leaf harvests within a short period.

Varieties
Coriander includes leaf types and seed types. Leaf varieties produce abundant tender foliage suited for fresh markets, while seed types produce larger seed heads preferred for spice processing. Improved varieties offer faster growth, uniform leaves, and better adaptation to local conditions. Variety selection influences aroma, yield, and market preference.

Growing Conditions
Coriander grows best in cool to moderately warm conditions with temperatures between 15–25 °C and rainfall of 500–1,000 mm. It performs well in fertile, well-drained loamy soils rich in organic matter with a pH of 6.0–7.0. Full sunlight supports strong leaf growth, while excessive heat triggers early flowering and reduces leaf production.

Growth Cycle
Coriander grows easily from seeds and forms soft green plants with finely divided leaves and slender stems. Small white flowers appear as the plant matures and later develop into round aromatic seeds. Its short growth cycle allows multiple planting seasons each year, ensuring a continuous supply.

Nutritional Value
Coriander leaves provide vitamins A, C, and K, antioxidants, and essential minerals that support digestion and immunity. The seeds also contain oils that aid flavor and digestion.

Uses & Market Potential
Coriander leaves serve as a fresh herb in salads, sauces, and traditional meals. The seeds are widely used as a spice in food processing and herbal products. Strong demand from fresh markets and spice traders creates steady commercial opportunities.
