The only basil I have tried to grow is the Purple basil.
Such pretty blooms:
Ocimum basilicum var. purpureum

It is really pretty and would make a great contrast with the colors of the other plants.
And this one with the contrast of purple flowers and green leaves is strikingly pretty:
Late summer Thai basil flowers

Thai basil, Ocimum basilicum var. thyrsiflora
It has been a long time since I grew basil that I don't remember the smell.
