The is your basic basil perfect for pesto!

They should emerge in 4 to 10 days. Make sure they can receive daily light once they have sprouted. Once danger of frost has past plant them in rich well drained soil about 10 inches apart.
If direct sowing only plant them after danger of frost has past. Plant seeds in rich well drained soil. Once they emerge thin down to one plant every 10 inches or so. Harvest leaves and enjoy.
