Just a quick look at our basil plants in the garden. The green is just a store bought plant (Lowes or Home Depot, I don’t remember) and the purple came from my Aero Garden. I planted them together to see how they would do and if there would be any change from cross pollination. I haven’t seen anything as of yet. None the less it makes for a beautiful look to the garden.
What is interesting though, is when you look at the purple basil leaves up close. Kelly showed this to me in a picture she took. All the purple leaves have a bright green edge.
