About Thai Basil
Thai Basil is an aromatic and flavour-rich variety essential to many Southeast Asian dishes, particularly Thai cuisine. The leaves have a slightly spicy, sweet flavour reminiscent of cinnamon and anise. Compact and beautifully ornamental, the plants have dark green leaves tinged with purple and bear striking spikes of pink-purple flowers throughout the summer. Thai Basil thrives in sunny, warm spots and is perfect for container growing or ornamental herb beds.
