Brussels Sprouts
Brassica oleracea gemmifera group
📖 About this plant
Brussels sprouts (Brassica oleracea gemmifera group) are a distinctive cool-season vegetable in the Brassicaceae family, prized for their unique appearance — miniature cabbage-like buds that form along a tall central stalk. Named after the city of Brussels in Belgium, where they were widely cultivated by the 16th century, Brussels sprouts are a cultivar group of the same species as cabbage, broccoli, cauliflower, and kale (Brassica oleracea). The plant develops a thick upright stem with large, broad leaves at the top and along the stem; the edible sprouts form in the leaf axils, maturing from the bottom of the stem upward. Sprouts are harvested when firm, green, and 2.5-5 cm in diameter. Brussels sprouts are nutritional powerhouses — rich in vitamins K and C, folate, fiber, and glucosinolates (sulfur compounds being studied for cancer-protective properties). The flavor improves markedly after a light frost, which converts starches to sugars — making them a popular late-autumn and winter crop in temperate regions. In India, Brussels sprouts are grown only in cool highland regions such as the Himalayan foothills, Nilgiris, and Kashmir Valley during the winter months. They are increasingly available in urban supermarkets and are used in continental cuisine, roasted, sautéed, or steamed.

💡 Care tips
- Sow seeds in mid-summer for autumn/winter harvest. Plant in firm, fertile, well-draining soil enriched with compost or well-rotted manure. Space plants 60 cm apart in rows 75 cm apart. Provide consistent moisture — dry spells cause bitter, loose sprouts. Stake tall plants to prevent wind damage. Remove lower leaves as sprouts mature from bottom upward to improve air circulation. Flavor sweetens after first frost — leave plants in the ground through light frosts. Harvest from the bottom of the stem upward, picking firm sprouts 2.5-4 cm across. In Indian highlands, grow during October-February when night temperatures drop below 15°C. Protect with netting from cabbage white butterflies. Practice 3-year crop rotation to prevent clubroot buildup.
