I planted some Thai basil this year because I had gotten some seed I-don't-know-why and I generally plant whatever I have seed for.
It's a small and very sweet smelling basil. And it blooms like crazy. All. Summer. Long.
We think it's OK, but prefer the Genovese style basil.
The bees, on the other hand, love it. Love. It.
I'll be planting rows and rows of it again just for them.
