Holy basil, also known as tulsi, is an aromatic basil grown for its warm, clove-scented leaves. Slightly fuzzy foliage and tall purple-green flower spikes give it a distinctive look, and the blooms draw in bees and butterflies late in the season. Ready in about 70 days, it is traditionally used in cooking and brewed into a fragrant herbal tea. Grow it in full sun for a fragrant, pollinator-friendly addition to the herb garden.
This is the quick guide to Holy (Tulsi). For the full step-by-step on starting seeds, sowing, feeding, and troubleshooting basil, see our complete guide to growing basil from seed.
Quick start
Start seeds indoors about 6 weeks before your last frost, sown a quarter inch deep in warm, moist mix at around 70F. Move plants outside only once nights stay above 50F, spacing them 12 to 18 inches apart in full sun. Keep the soil evenly moist and pinch the tips to keep the plant bushy. Begin harvesting leaves in about 70 days, pinching or leaving flower spikes depending on your goal.
Best tip
For the most tender leaves, pinch off the flower spikes; to feed pollinators, let some plants bloom for the bees and butterflies. Climate matters most at the edges of the season: holy basil is very cold-sensitive, so gardeners in the Northeast and Midwest should wait until nights stay above 50F before setting plants out, while growers in the Deep South, Texas, and Southern California get a long, productive run and mainly need steady water through the hottest weeks.

Holy basil is prized for its warm, clove-like aroma. Brew the fresh or dried leaves into a fragrant herbal tea, and add them to soups, stir-fries, and other savory dishes for a spicy, peppery lift. In the garden, its purple flower spikes are a pollinator favorite, drawing bees and butterflies late in the season. Pick leaves before heavy flowering for the strongest fragrance.
What is holy basil (tulsi) used for?
Holy basil, also called tulsi, is prized for its aromatic, clove-scented leaves. It is traditionally brewed into a fragrant herbal tea and used to flavor cooking, and it is a well-loved plant in the herb and pollinator garden. Its flowers draw in bees and butterflies through late summer.
How is holy basil different from regular basil?
Holy basil has a warm, clove-like, slightly peppery aroma rather than the sweet flavor of Genovese basil, and its leaves are often a bit fuzzy with tall purple-green flower spikes. It is grown more for tea and fragrance than for pesto, and it tends to be a little more heat-tolerant.
How long does holy basil take to grow?
Holy basil is ready to begin harvesting in about 70 days from sowing. Like other basils it germinates in 5 to 10 days in warm, moist soil, and once plants are bushy you can pick leaves regularly for tea and cooking.
Should I let holy basil flower?
It depends on your goal. If you want the most tender leaves for tea and cooking, pinch off the flower spikes to keep the plant producing foliage. If you want to support pollinators, let some plants bloom, since the flowers are very attractive to bees and butterflies late in the season.
