Product Description
Thai Basil Seeds
Thai Basil Seeds produce attractive plants with small, narrow green leaves, distinctive purple stems, and beautiful mauve to pink-purple flowers. This aromatic culinary basil has a characteristic liquorice-like flavour that makes it particularly useful for Asian-inspired cooking.
Thai Basil thrives in rich, well-drained soil in a warm and sheltered position. The leaves are best picked as required and used fresh for maximum flavour. Its colourful stems and flowers also make it an attractive addition to kitchen gardens, greenhouse displays, and sunny windowsills.
Pinching out the tip of the main stem encourages compact, bushy growth. Flower buds can also be removed if you want the plants to concentrate their energy on producing plenty of fresh leaves.

How to Grow Thai Basil Seeds
Sow Thai Basil Seeds indoors from March, approximately 0.5cm deep in good-quality seed compost.
Several seeds can be sown together in each pot. Once established, plants can be potted on and grown on a bright kitchen windowsill or transferred into 1–2 litre pots for growing alongside tomatoes in the greenhouse.
Plants can be grown outdoors from late May, once all risk of frost has passed. Space plants approximately 30cm apart in rich, well-drained soil in a warm, sheltered position.
Alternatively, sow directly outdoors in drills during May once the soil has warmed, thinning seedlings to approximately 30cm apart.
Thai Basil can also be grown all year round on a bright windowsill, providing fresh aromatic leaves close to the kitchen.
