Fresh basil is fragrant, spicy, and a traditional herb in summer cuisine. And while you may only know one of a few types of basils from what you can get at the grocery store, there are up to 150 basil varieties, most deriving from Ocimum basilicum (sweet basil). It can grow from 10 to 24 inches tall, depending on the variety.
This annual herb from the mint family likes plenty of sun, though it will tolerate a bit of shade, and does best in well-drained, rich, loamy soil. It's native to Asia and Africa and is perennial in warm zones USDA 9 to 11, but is primarily grown as an annual. It can be planted outdoors in spring after the last frost.

Tips for Growing Basil
Basil loves the sun, but if you notice wilting during days of harsh sun, give shade or water more thoroughly. Basil plants like regular water.
Basil germinates 7 to 10 days after planting and is usually ready for harvest within three to four weeks.
Basil grows indoors or outdoors; it only needs six to eight hours of steady sunlight to grow well.
Prune basil monthly (1/3 of the leaves) to encourage bushier, healthier growth.
Avoid bolting or the plant producing flowers and seeds by reducing its exposure to intense heat; pinch off the flowering stems 1 inch below the bud to prevent them from tasting bitter.
Do not fertilize basil; too many nutrients can make basil lose its signature taste.
