About Holy Basil (Tulsi)

Holy basil (tulsi) is one of the most sacred plants in Hinduism and a cornerstone of Ayurvedic medicine. The clove-pepper flavoured leaves are used in Indian cooking, teas, and as a medicinal herb. Grows happily in a pot on a sunny windowsill in any climate.

Start indoors 4-6 weeks before last frost. Grow in a sunny window year-round in cold climates. Harvest before flowering to maintain flavour. Pinch flower buds regularly. Three varieties worth growing: Rama (mild), Krishna (purple, spicier), Vana (wild-type, very aromatic).
