Thai Basil leaves tastes more aniseed than the common basil we get here in supermarkets and in Italian cooking. It is grown very much like common Basil except when it flowers it has nice deep purple flowers. The leaves has a different shape as well. Easy to grow, needs full sun, Some gardening books recommend to start sowing the seeds in April or early May. I have started sowing the seeds in April look how much they have grown. Just keep harvesting just only the leaves as it will give room for new leaves to grow.
