I'm sure this is more than you ever wanted to know about Basil...But I really learned a lot while researching this herb. I hope you have fun planting, and experimenting with this herb...Just the fragrance alone is wonderful, but cooking with fresh herbs makes a world of difference in your food.
I want to add here that I was having an awful time finding "the right" background for my herb page, and out of frustration I asked this wonderful person if they could maybe create something for me, with a slight description of "something with Basil, Rosemary and Lavender"..well you see the wonderful results. I can't thank Lolis enough for this. If you are looking for something beautiful, subtle, elegant and creatively different, please stop by this site, you will not be disappointed, I know I never have. Thanks again Lolis.
