Regularly, the more you harvest the more it will produce. If kept warm and harvested often you may even get 10 months worth of Basil leaves. Choose a sunny site with well-drained soil, amend with well-rotted manure or compost. Basil Sweet, originally from India, is best known as a culinary herb prominently featured in Italian cuisine, and also plays a major role in the Northeast Asian cuisine of Taiwan and the Southeast Asian cuisines of Thailand, Vietnam, Cambodia, and Laos. Depending on the species and cultivar, the leaves may taste somewhat like anise, with a strong, pungent, often sweet smell.
