Ocimum basilicum, commonly known as sweet basil, is a culinary herb from the mint family, Lamiaceae. It's native to tropical regions from central Africa to Southeast Asia and is a tender annual, meaning it completes its life cycle (from germination to producing seeds) within one year and is sensitive to cold temperatures.

Varieties: There are many varieties of basil available, ranging in flavor from lemony to spicy, and in colors from green to purplish-black. Examples include Genovese, Thai, Purple Ruffles, and Lemon Basil.

Cultivation: Basil is typically grown as an annual in temperate climates because it's not frost-tolerant. It thrives in well-draining soil and full sunlight. The plant should be watered regularly, but it doesn't like to be sitting in water.

Propagation: Basil is typically grown from seeds, but it can also be propagated from cuttings. Once the plant starts to flower, it's a good idea to pinch off the flowering tops to encourage the plant to produce more leaves.

Companion Planting: In gardening, basil is often planted alongside tomatoes, as it's believed to improve the flavor of the tomatoes and repel pests like mosquitoes and tomato hornworms.

Pest Issues: Basil can be susceptible to pests like aphids, whiteflies, and fusarium wilt. Regularly checking plants and using natural pest control methods can help.
