Sage is a perennial herb grown for its aromatic leaves, used in cooking, teas, and herbal medicine. It has a strong earthy flavour and plays a key role in seasoning meat dishes, soups, and sauces. In Kenya, sage grows well in cool highland and irrigated areas such as Kiambu, Nakuru, Nyandarua, Nyeri, and Meru. The plant forms small woody shrubs with grey-green leaves that can be harvested repeatedly. Strong demand from restaurants, herbal product makers, and supermarkets supports its growing value as a niche herb crop.

Varieties
Common sage types include culinary sage (Salvia officinalis), purple sage, and golden sage. These varieties differ in leaf colour, aroma strength, and growth habit. Culinary sage produces the strongest flavour for cooking, while purple and golden types serve both culinary and ornamental purposes. Variety choice depends on market demand and intended use.

Growing Conditions
Sage grows best in cool to moderate temperatures of 15–25 °C and rainfall of 500–1,000 mm. It thrives in well-drained, slightly sandy or loamy soils rich in organic matter with a pH of 6.0–7.5. The plant prefers full sunlight and dry conditions. Excess moisture reduces oil content and increases root rot risk.

Growth Cycle
Sage grows from cuttings or seeds and develops into compact woody shrubs. It produces elongated stems with grey-green leaves that can be harvested continuously once established. Regular pruning encourages bushy growth and improves leaf production.

Nutritional Value
Sage contains antioxidants, vitamins A and K, and essential oils such as thujone. These compounds support digestion, memory, and immune health.

Uses & Market Potential
Sage is used fresh or dried in cooking, teas, and seasoning blends. It also supports herbal medicine and essential oil production. Growing demand in food, wellness, and culinary markets creates steady opportunities for commercial herb production and value addition.
