Chilli
Capsicum annuum
📖 About this plant
Chilli (Capsicum annuum), known in Hindi as mirch and one of the most defining ingredients of Indian cuisine, is a fruit-bearing plant from the Solanaceae family. Native to Central and South America, chillies were brought to India by the Portuguese in the late 15th century and quickly became indispensable to Indian cooking, medicine, and culture — so much so that India is today the worlds largest producer, consumer, and exporter of chillies. The plant produces white flowers followed by fruits that range widely in size, shape, color (green to red when ripe), and pungency — measured in Scoville Heat Units (SHU) from the mild bell pepper (0 SHU) to the scorching Bhut Jolokia/Ghost Pepper (over 1,000,000 SHU). Chillis pungency comes from capsaicin, a compound concentrated in the placenta (white pith) and seeds. Beyond culinary use, capsaicin has well-documented medicinal properties — it boosts metabolism, relieves pain topically, supports cardiovascular health, and triggers endorphin release. India grows dozens of cultivars, including Kashmiri chilli (mild, deep red color), Byadgi (Karnataka), Guntur Sannam (Andhra), and the legendary Bhut Jolokia from Assam. The plant thrives in warm, sunny conditions and is a staple of kitchen gardens across the subcontinent.

💡 Care tips
- Start seeds indoors 8-10 weeks before the last frost; transplant when soil is warm and seedlings have 6-8 true leaves. Plant in full sun in fertile, well-draining soil. Space plants 45-60 cm apart. Water consistently but avoid waterlogging — chillies hate wet feet. Mulch to retain moisture and warm the soil. Feed with potassium-rich fertilizer during flowering and fruiting; avoid excess nitrogen which produces leaves at the expense of fruit. Stake tall varieties. Pinch the first flowers to encourage stronger root development. Harvest green chillies any time after they reach full size; for red ripe chillies, leave on the plant until color deepens. Wear gloves when handling hot varieties — capsaicin burns skin and eyes. Rotate crops to prevent soil-borne diseases. In Indian home gardens, chilli grows year-round in frost-free regions.
