Basil is one of the most well known of the world's herbs. Basil thrives in warm, sunny climates. Grows best in an outdoor environment with exposure to five or more hours of sunlight each day, but can be cultivated indoors in pots, as well. Basil needs plenty of sunlight to grow and flower, so make sure it is in a bright place. Basil is commonly used fresh in cooked recipes. It is generally added at the last moment, as cooking quickly destroys the flavour. The fresh herb can be kept for a short time in plastic bags in the refrigerator.
