Tulsi Kapoor | Ocimum tenuiflorum

Tulsi has been called the Queen of Herbs in Ayurvedic tradition for thousands of years, and Kapoor is the variety most prized for medicinal use — compact, intensely aromatic, green-leaved with a fruity, clove-forward fragrance that stops you the moment you brush past it. In Ayurveda it sits at the center of daily wellness practice: an adaptogen that helps the body regulate stress, an immunomodulator, antiviral, antibacterial, and anti-inflammatory all at once. The research backs the tradition — studies have documented its effects on cortisol, blood sugar, blood pressure, cholesterol, and respiratory health. It's primarily used as tea, steeped fresh or dried, and the flavor is genuinely good — peppery, floral, slightly sweet. It also has a long history of spiritual significance in Hindu practice, where growing and tending it is considered an act of devotion.

In Zone 8 and colder, it grows as a warm-season annual — start it after last frost in full sun, keep it well-watered, pinch the flowers to extend leaf production, and let it self-seed for next year. Deer and rabbits leave it alone. Pollinators love the flowers when you do let it bloom.
