About Holy basil

Holy Basil (Ocimum tenuiflorum), also known as Tulasi, is an aromatic perennial herb revered for its medicinal properties and distinct fragrance. Its oval-shaped leaves, ranging from green to purple, are arranged on square stems, and it produces small white or purplish flowers on spikes. It's ideal for herb gardens, pots on sunny balconies, or as part of a medicinal herb collection.

Care tips

It requires full sun (at least 6 hours daily) for optimal growth and good essential oil production. Watering should be regular, keeping the soil moist but not waterlogged, especially in warm climates. It prefers well-draining, rich organic soil. A common mistake is insufficient light, leading to leggy and less aromatic growth.
