Thai basil is very easy to grow from seed. It germinates within a few days, and is very tough and resistant to pests and fungi (unlike Sweet basil, which is attacked by everything, it seems). I start mine in the late spring, harvest through summer, and then, by late fall, it's gone. Annuals make me sad when they leave after a few short months, but I save seed from the flower heads and start again the next spring. It's worth a spot in an herb garden whether the cook likes Thai food or not.
