Well, Madonnaswimmer - you have waited over 48 hours without getting a detailed explanation of the difference between the 2.
You can already read between the lines of what I said 6 weeks ago, I don't see a reason to separate out a "sweet" basil the way it is often done.
So . . . this isn't much of an answer to your question either .
BTW - It is a couple weeks before there's any reason to really fret about it but - I'm still waiting for that Red Genovese seed to show up . . .
