Thai basil is a mainstay of Southeast Asian cooking with its distinctive bold flavours of liquorice and spice. It is easy to grow and care for in a herb garden or even a windowsill with a neat, upright habit, perfect for baskets and pots. It differs from sweet basil with its distinctive reddish-purple stems, cross-shaped green leaves, and pink and purple flowers that appear in the late summer. A tender perennial herb, it is best sown and grown annually.
