Donner-
Did your Basil bloom? If you allowed it to bloom--it will make seed.
I just grew Thai Basil this year. Thy have such pretty purple blooms...
Right now--because of the warm weather--there is a lot of foliage growing on the basil. I will pick most of the leaves off--and let them dry.
I almost never, use basil in cooking....I just like the way it smells...
The Thai basil also has pretty blooms.
This is the basil I have the most seeds from. Don't ask me why I even grow it!!! I don't even make Pesto. Aina does--so I will grow more of it for her.
