Organic Sweet Thai Basil Seeds with Spicy, Licorice Aroma

Organic Sweet Thai basil seeds grow into highly aromatic plants with glossy green leaves, thick purple stems, and edible purple flower spikes. Widely used in Thai, Vietnamese, and other Southeast Asian cuisines, this basil variety is prized for its bold, spicy flavour that holds up exceptionally well in cooked dishes. 

Thai Basil vs. Basil

Thai basil differs from common sweet basil in both flavour profile and culinary performance. Thai basil contains higher levels of anethole, giving it a distinct licorice-like, slightly spicy aroma, while sweet basil is milder and more clove-like due to higher eugenol content. Thai basil has firmer leaves and sturdy purple stems and retains its flavour when exposed to heat, making it ideal for curries, stir-fries, and soups. Sweet basil is more delicate and is best used fresh or lightly cooked, as prolonged heat quickly diminishes its aroma.

FAQs

How do I grow Thai basil from seed?

In order to grow Thai basil from seed, you need to start seeds indoors 4–8 weeks before the last frost or direct sow outdoors once soil temperatures reach at least 21°C (70°F). Thai basil requires warm conditions, full sun, and well-drained soil for best results.

Does Thai basil need pinching?

Yes, pinching Thai basil plants once they reach about 15 cm (6") tall encourages branching and helps produce a fuller plant with a continuous supply of leaves.

Can Thai basil be grown in containers?

Thai basil grows very well in containers, provided it receives full sun, warm temperatures, and consistent watering.
