Yum ~ basils! I agree with Critterologist on the small leaf basils. My favorite is Pistou.
A larger leaf favorite from last year was licorice basil but then I am a licorice fan.
I do like camphor too but have not seen a camphor basil Tropicalover. Sounds interesting.
A new one I'm trying this year but didn't get great germination is Yeome basil. Think I spelled it right. I have two little plants in ground and they have a interesting fragrance.
I wasn't aware the seeds would not remain viable longterm but resist saving much seed as it will cross freely with the other basils. What I wanted to save isn't always what I ended up saving. lol
